Description

9,10-Dihydro-9,10-Dihydroxybenzo(A)Pyrene is a key dihydrodiol metabolite of benzo[a]pyrene, a well-studied polycyclic aromatic hydrocarbon (PAH). This compound is of significant interest in biochemical and toxicological research as a critical intermediate in the metabolic activation pathway of carcinogenic PAHs. It serves as an essential reference standard and analytical reagent for laboratories investigating environmental pollution, metabolic pathways, DNA adduct formation, and chemical carcinogenesis. The product is supplied with a CAS number of 24909-09-9.

Application

• Biochemical Research Standard: Used as a high-purity analytical standard for calibrating equipment and quantifying metabolites in complex biological matrices.
• Toxicology Studies: Critical for investigating the metabolic activation, detoxification, and carcinogenic mechanisms of benzo[a]pyrene and related PAHs.
• Environmental Analysis: Employed in method development and validation for detecting and monitoring PAH metabolites in environmental and occupational exposure samples.
• DNA Adduct Research: Serves as a precursor in studies examining the formation and repair of DNA adducts, which are critical events in chemical carcinogenesis.
• Enzymology Assays: Used as a substrate to study the activity and kinetics of cytochrome P450 enzymes and epoxide hydrolase involved in PAH metabolism.
• Pharmaceutical Intermediates: Potential use as a building block or reference compound in the development of chemopreventive agents or metabolic inhibitors.
