Description

(-)-trans-Heptachlorepoxide CAS NO 76986-14-6 is a specific stereoisomer of heptachlor epoxide, a persistent organic pollutant and metabolite of the insecticide heptachlor. This compound is of significant importance as a high-purity analytical reference standard for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, regulatory agencies, and research institutions involved in the detection, quantification, and study of organochlorine pesticide residues in soil, water, and biological samples to ensure compliance with environmental and food safety regulations.

Application

• Primary use as a certified analytical reference standard for calibration and quality control in chromatographic analysis (GC, GC-MS, LC-MS).
• Critical component in environmental monitoring programs for the detection of heptachlor and its metabolites in compliance with global POPs (Persistent Organic Pollutants) regulations.
• Essential material for toxicological and ecotoxicological studies to understand the environmental fate, bioaccumulation, and health effects of organochlorine compounds.
• Used in the development and validation of analytical methods for pesticide residue analysis in food, feed, and agricultural products.
• Supplies forensic and diagnostic laboratories for exposure assessment in human and wildlife tissue samples.
• Serves as a key reagent in research on degradation pathways and remediation strategies for contaminated sites.
