Analytical Standard Grade

Certified Reference Materials for Quantitative and Qualitative Analysis


Analytical Standard Grade products from Aladdin Scientific are high-purity chemicals and solutions developed for use as primary or secondary reference standards in a wide range of analytical testingmethod validation, and instrument calibration workflows. Each compound is supplied with full documentation supporting its use in traceable, reproducible, and regulated analytical applications.


Key Features

· High Chemical Purity (Typically ≥99.5%)
Precisely characterized and controlled to ensure lot-to-lot reproducibility.

· Accurate Composition and Traceability
Identity and concentration verified by NMR, HPLC, GC, MS, KF, or titration methods. Traceable to international or pharmacopeial reference materials (where applicable).

· Accompanied by Detailed Certificate of Analysis (CoA)
Includes molecular identity, purity, assay method, water content, residual solvents, and measurement uncertainty (for certified reference materials).

· Stability and Packaging
Packaged under inert atmosphere or sealed in ampoules to preserve stability and concentration over time. Suitable for long-term archival and use in regulated environments.


Typical Applications

· Calibration of analytical instruments (HPLC, GC, LC-MS, UV-Vis)

· Standard curve generation for quantitative assays

· Method validation and system suitability testing

· Regulatory and compendial testing (e.g., pharmacopeial, environmental, forensic)

· Control of process consistency in QA/QC laboratories


Available Formats

· Neat solids or liquids (≥99.5% purity)

· Pre-weighed ampoules or solution standards (e.g., 1000 µg/mL in MeOH or ACN)

· Custom concentrations, blends, and multi-component standards available on request


Why Choose Aladdin Analytical Standards?

· Manufactured in ISO-compliant and traceable labs

· Backed by complete characterization and validated methodology

· Ideal for use in GLP, GMP, ISO/IEC 17025, and regulatory compliance testing

· Supplied with CoA and optional SDS, IR/NMR/MS spectra
