What Is Gamma-BHC Solution and What Does It Contain?

Gamma-BHC solution is a reference-grade preparation of gamma-hexachlorocyclohexane—commonly known as lindane or gamma-BHC—dissolved in a suitable organic solvent such as isooctane, hexane, or acetone. Gamma-BHC is one of eight stereoisomers of benzene hexachloride (BHC, hexachlorocyclohexane) and is the isomer with the highest insecticidal activity. As a solution standard (SKU: B101463), it is manufactured to support accurate quantitative analysis rather than for pesticidal use.

The active constituent, gamma-hexachlorocyclohexane (CAS 58-89-9), is a chlorinated alicyclic compound historically employed as an agricultural insecticide. In its standard-solution form, it is supplied at a defined nominal concentration to facilitate direct use in instrument calibration and method development without the need for additional weighing or dissolution steps.

Key Analytical Applications of Gamma-BHC Solution

Gamma-BHC solution is principally used as a calibration standard and quality-control reference in chromatographic methods for pesticide residue analysis. Typical applications include:

• Gas chromatography (GC) with electron capture detection (ECD): Lindane responds strongly to ECD owing to its multiple chlorine substituents, making it a classical target analyte and system-suitability compound in organochlorine pesticide panels.
• GC-MS and GC-MS/MS: Used for confirmatory identification and quantification of lindane in food, water, soil, and biological matrices in accordance with regulatory methods (e.g., EPA, EU, Codex Alimentarius frameworks).
• Method validation and proficiency testing: Laboratories use certified or traceable solutions to prepare spiking solutions, verify recovery rates, and demonstrate method performance.
• Environmental monitoring: Monitoring of lindane in surface water, groundwater, and sediment as required under environmental legislation governing persistent organic pollutants.

Because lindane is a scheduled substance under the Stockholm Convention, its use as an analytical standard is subject to relevant national import, storage, and disposal regulations.

Storage, Stability and Handling Precautions

Storage: Gamma-BHC solution should be stored in tightly sealed containers in a cool (typically 2–8 °C or as specified on the product label), dark, and well-ventilated area, away from heat sources, open flames, and incompatible materials such as strong oxidizers. Solvent-based solutions are flammable; handle away from ignition sources.

Stability: When stored under recommended conditions and protected from light, organochlorine standard solutions are generally stable for the duration of the stated shelf life on the certificate of analysis. Repeated freeze-thaw cycles and exposure to UV light should be avoided as they may alter analyte concentration.

Personal protective equipment (PPE): Handle in a chemical fume hood. Wear appropriate chemical-resistant gloves, safety goggles, and a laboratory coat. Lindane is classified as toxic and a potential carcinogen; skin and inhalation exposure must be minimized.

Disposal: Dispose of as hazardous chemical waste in accordance with local, regional, and national regulations governing organochlorine compounds. Do not pour down the drain.

Always consult the Safety Data Sheet (SDS) supplied with SKU B101463 before first use.

Quality, Traceability and Ordering Information

Quality assurance: Analytical standard solutions for pesticide residue work are expected to carry a certificate of analysis (CoA) documenting the confirmed concentration, solvent identity, preparation date, expiry date, and uncertainty where applicable. Researchers and laboratory managers should verify that the CoA is available and matches the specific lot received.

Traceability: For regulated testing (food safety, environmental compliance), it is advisable to use solutions with concentration values traceable to a recognized national metrology institute (NMI) or certified reference material (CRM). Procurement teams should confirm the traceability chain when selecting lots for regulatory submissions.

Ordering Gamma-BHC solution from Aladdin Scientific: Gamma-BHC solution is listed under SKU B101463. To place an order, contact Aladdin Scientific through the website product page, by email, or through your regional distributor. Provide the SKU, required pack size, and any purity or concentration specifications needed for your application. Lead times, pricing, and availability can be confirmed by the Aladdin sales team.

Import and regulatory compliance: Because lindane is a controlled substance in many jurisdictions, customers are responsible for ensuring they hold any required permits or authorizations before ordering. Aladdin Scientific recommends consulting applicable regulations prior to purchase.

Frequently asked questions

What concentration is Gamma-BHC solution (SKU B101463) supplied at?

The nominal concentration and solvent composition are specified on the product label and certificate of analysis for each lot. Please refer to the CoA accompanying your shipment or contact Aladdin Scientific for lot-specific details, as these parameters may vary by pack size or catalog version.

Which analytical techniques are most commonly used with Gamma-BHC solution?

Gamma-BHC solution is most commonly used with gas chromatography coupled to electron capture detection (GC-ECD) or mass spectrometric detection (GC-MS, GC-MS/MS). These techniques provide the sensitivity and selectivity required for trace-level organochlorine pesticide analysis in food, environmental, and biological matrices.

Is Gamma-BHC solution hazardous, and what safety precautions should I take?

Yes, gamma-BHC solution is hazardous. Lindane is classified as toxic by ingestion, inhalation, and skin contact, and is a suspected carcinogen. The organic solvent carrier also presents flammability hazards. Always handle in a fume hood, wear chemical-resistant gloves and eye protection, and consult the SDS for SKU B101463 before use.

Does Gamma-BHC solution require any special import permits?

Lindane is listed as a persistent organic pollutant under the Stockholm Convention and is subject to import restrictions or bans in many countries. Customers are responsible for determining and obtaining any required permits or authorizations from their national regulatory authorities before placing an order. Aladdin Scientific recommends consulting local regulations prior to purchase.

How should I dispose of unused Gamma-BHC solution?

Unused Gamma-BHC solution must be treated as hazardous chemical waste. Dispose of in accordance with all applicable local, regional, and national regulations governing organochlorine and halogenated solvent wastes. Do not pour down the drain or dispose of in general laboratory waste. Contact your institutional environmental health and safety office for guidance.
