Overview and Intended Application

Lomatin (SKU L1064078) is a coumarin-derived natural product available from Aladdin Scientific for in vitro research purposes. Coumarins are a structurally diverse class of benzopyrone secondary metabolites isolated from a variety of plant sources and have been studied in the context of enzyme inhibition, antioxidant activity, and other biological investigations. Lomatin itself has been of interest to researchers examining the bioactivities of furanocoumarins and related scaffolds.

This reagent is supplied exclusively for laboratory research use. It must not be used in any diagnostic, therapeutic, food, drug, cosmetic, or household product application. All users should consult the applicable Safety Data Sheet (SDS) before working with this compound.

Safe Handling Procedures

When handling Lomatin, adhere to standard laboratory safety practices appropriate for small-molecule organic compounds of plant origin:

• Personal Protective Equipment (PPE): Wear nitrile gloves, a laboratory coat, and safety goggles at all times. If operations may generate dust or aerosols, use a particulate respirator or work inside a chemical fume hood.
• Weighing and Dissolution: Perform weighing in a fume hood or biosafety cabinet to minimise inhalation exposure. Use a calibrated analytical balance and pre-tared vessels to avoid unnecessary compound loss.
• Spill Management: In the event of a spill, contain the material with an inert absorbent, collect into a labelled waste container, and clean the surface with an appropriate solvent. Report spills according to institutional procedures.
• Waste Disposal: Dispose of Lomatin and associated solvent waste in accordance with local, regional, and national regulations governing hazardous chemical waste. Do not dispose of down the drain.

Note: Specific acute toxicity, GHS classification, and first-aid data for Lomatin should be confirmed from the current Aladdin Scientific SDS (L1064078) before use, as detailed hazard characterisation requires review.

Storage and Stability Conditions

Proper storage is critical to maintaining the chemical integrity and research-grade quality of Lomatin over time. Follow these general guidelines unless the product label or SDS specifies otherwise:

• Temperature: Store at −20 °C for long-term preservation, or at 2–8 °C for short-term working stocks. Avoid repeated freeze-thaw cycles, which can accelerate degradation.
• Container and Atmosphere: Keep the original tightly sealed container. For moisture-sensitive or oxygen-sensitive compounds, store under inert gas (argon or nitrogen) and use desiccant where appropriate.
• Light Exposure: Coumarin-class compounds can be susceptible to photodegradation. Store in amber vials or in the dark to minimise UV-induced decomposition.
• Shelf Life: Consult the product Certificate of Analysis (CoA) and current label for the confirmed shelf life and re-test date. Contact Aladdin Scientific technical support for stability queries specific to L1064078.

Flag: Specific confirmed storage temperature, shelf life, and photostability data for Lomatin L1064078 are not available in the source material and require verification from the CoA or SDS.

Stock Solution Preparation

Preparation of a high-quality stock solution ensures reproducibility across experiments. The following protocol represents general best practice for coumarin-class compounds; users must verify suitability for Lomatin based on empirical solubility testing:

1. Determine Target Concentration: Based on your assay requirements, calculate the mass of Lomatin needed using the formula: mass (mg) = concentration (mM) × volume (mL) × molecular weight (g/mol) ÷ 1000. (Note: confirm the molecular weight from the CoA for L1064078; source material does not specify this value.)
2. Solvent Selection: DMSO is commonly used as a primary solvent for hydrophobic natural products. Prepare a concentrated stock (e.g., 10–50 mM) in anhydrous DMSO, then dilute into aqueous assay buffer to the desired working concentration. Keep final DMSO concentration ≤0.1% (v/v) in cell-based assays to avoid vehicle toxicity, or as determined by solvent controls.
3. Sonication: If complete dissolution is not immediately achieved, briefly sonicate the solution in a water bath sonicator (2–5 min) at room temperature.
4. Aliquot and Store: Divide the stock solution into single-use aliquots in amber microcentrifuge tubes. Store at −20 °C and protect from light. Label each tube with compound name, SKU, concentration, solvent, and preparation date.
5. Sterile Filtration: For cell culture work, filter through a 0.22 µm PVDF syringe filter after dissolution and before aliquoting.

Quality Control and Troubleshooting

Maintaining reagent quality and troubleshooting common issues is essential for reliable experimental outcomes when using Lomatin.

Verifying Purity: Review the Certificate of Analysis (CoA) supplied with each lot of L1064078 for purity data (typically assessed by HPLC). If identity confirmation is required, use techniques such as NMR, LC-MS, or UV spectrophotometry benchmarked against literature spectral data for Lomatin.

Precipitation in Aqueous Buffer: If Lomatin precipitates upon dilution into aqueous media, try the following: (1) pre-warm the buffer to 37 °C; (2) reduce the final compound concentration; (3) use co-solvents such as PEG-400 or hydroxypropyl-β-cyclodextrin where compatible with your assay; (4) re-evaluate whether a different primary solvent improves aqueous miscibility.

Unexpected Biological Activity Variation: Batch-to-batch variation in natural products can influence biological assays. Always run positive and negative controls, and record the lot number in experimental notes for traceability.

Frequently asked questions

What is Lomatin and what is it used for in research?

Lomatin is a coumarin-class natural product (SKU L1064078) supplied by Aladdin Scientific for in vitro research purposes. It has been studied in contexts including enzyme inhibition and bioactivity profiling of furanocoumarin scaffolds. It is intended strictly for laboratory research use and not for diagnostic or therapeutic applications.

How should Lomatin (L1064078) be stored to preserve its stability?

For long-term storage, keep Lomatin at −20 °C in a tightly sealed container, protected from light and moisture. For short-term use, 2–8 °C storage may be acceptable. Avoid repeated freeze-thaw cycles. Always consult the current product label and Certificate of Analysis for lot-specific storage recommendations, as confirmed stability data requires review.

What solvent is recommended for dissolving Lomatin?

DMSO is generally recommended as the primary solvent for hydrophobic coumarin-class compounds like Lomatin. Prepare a concentrated stock solution in anhydrous DMSO, then dilute to the required working concentration in aqueous assay buffer. Verify actual solubility empirically before use, and ensure the final DMSO concentration is compatible with your assay system.

Where can I obtain the Safety Data Sheet (SDS) and Certificate of Analysis (CoA) for L1064078?

The SDS and CoA for Lomatin (L1064078) are available through the Aladdin Scientific official website by searching the SKU. For lot-specific CoA documents or additional technical enquiries, contact Aladdin Scientific customer and technical support directly.

Is Lomatin suitable for in vivo studies?

Lomatin (L1064078) is classified as a research-use-only reagent and has not been evaluated or approved for in vivo diagnostic or therapeutic use. Any application outside standard in vitro laboratory research requires independent validation, full hazard assessment, and compliance with all applicable institutional and regulatory requirements.
