Description

β-1,2,3,4,5,6-Hexachlorocyclohexane is a specific stereoisomer of hexachlorocyclohexane (HCH), a chlorinated hydrocarbon compound. This high-purity isomer is critical for research and development applications, particularly in analytical chemistry and environmental science, where precise chemical standards are required. It serves as an essential reference material for laboratories studying the degradation, environmental fate, and toxicology of HCH isomers.

Application

• Analytical Reference Standard: Primary use as a certified standard for gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) in environmental and food safety testing.
• Environmental Research: Used in studies to understand the behavior, persistence, and breakdown pathways of HCH isomers in soil and water systems.
• Toxicological Studies: Serves as a precise reagent in laboratory research to investigate the biological effects and metabolic pathways of specific HCH isomers.
• Method Development & Validation: Essential for developing and calibrating analytical methods for the detection and quantification of organochlorine pollutants.
• Chemical Synthesis Intermediate: Can be utilized in specialized organic synthesis for producing other chlorinated compounds or degradation products for study.
• Quality Control: Employed by manufacturers and testing facilities as an internal standard to ensure accuracy in pesticide residue analysis.
