Description

γ-Hch-D6 is a deuterium-labeled isotopologue of γ-hexachlorocyclohexane (γ-HCH, Lindane), specifically designed for use as an internal standard in analytical chemistry. This high-purity compound is essential for ensuring accurate quantification and method validation in trace-level analysis, compensating for matrix effects and instrument variability. It is a critical tool for environmental testing laboratories, agrochemical researchers, and regulatory bodies requiring precise measurement of HCH isomers and their residues.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative internal standard in GC-MS and LC-MS/MS analysis for the accurate determination of γ-HCH and related organochlorine pesticides.
• Environmental Monitoring and Analysis: Used in the testing of soil, water, and air samples to monitor pollution levels and assess environmental contamination from historical pesticide use.
• Food Safety and Residue Testing: Employed in laboratories to quantify pesticide residues in food products, ensuring compliance with maximum residue limits (MRLs) set by global regulatory agencies.
• Metabolite and Degradation Studies: Serves as a stable isotope tracer in research to study the environmental fate, biodegradation pathways, and metabolic products of HCH isomers.
• Forensic and Regulatory Analysis: Provides a reliable reference for confirming the identity and concentration of γ-HCH in samples analyzed for legal or compliance purposes.
• Method Development and Validation: Critical for developing, optimizing, and validating new analytical methods according to guidelines such as those from the EPA, FDA, and ISO.
• Quality Control in Reference Material Production: Used in the preparation and certification of certified reference materials (CRMs) and quality control samples for laboratory proficiency testing.
