Product Description:

Δ-Hexachlorocyclohexane (δ-HCH, CAS 319-86-8) is one of the eight stereoisomers of 1,2,3,4,5,6-hexachlorocyclohexane. It is a persistent organic pollutant (POP) and a component of technical-grade hexachlorocyclohexane (HCH), which was historically used as a broad-spectrum insecticide. Its molecular formula is C6H6Cl6. The primary historical application of δ-HCH was as an insecticidal component within technical HCH mixtures. However, its insecticidal activity is significantly lower than that of the γ-isomer (lindane). Due to its high persistence, bioaccumulation potential, and toxicity, the production and agricultural use of technical HCH and lindane have been severely restricted or banned globally under the Stockholm Convention on POPs. Today, δ-HCH is primarily studied as an environmental contaminant. It is a stable, solid compound at room temperature and is often found as a residue in soil and water from past applications. Research focuses on its environmental fate, degradation pathways, and ecotoxicological effects rather than its original pesticidal use.
