Description

(3S)-3,4-Dihydrobenzo[A]Anthracene-3α,4β-Diol CAS NO 67335-43-7 is a high-purity, stereospecific dihydrodiol derivative of benzo[a]anthracene. This compound is a critical intermediate in advanced organic synthesis and biochemical research, valued for its defined stereochemistry and role as a precursor to more complex polycyclic aromatic hydrocarbon (PAH) metabolites. It is primarily utilized by research institutions and industrial R&D laboratories focused on environmental toxicology, carcinogenesis studies, and the development of analytical standards.

Application

• Biochemical Research Intermediate: Serves as a key precursor in the synthesis of stereospecific PAH metabolites for studying metabolic activation pathways and DNA adduct formation.
• Environmental Toxicology Studies: Used as a reference standard or starting material in research investigating the metabolic fate and biological impact of polycyclic aromatic hydrocarbons.
• Analytical Standard Development: Employed in the preparation of certified reference materials (CRMs) for calibrating analytical instruments like HPLC and GC-MS in environmental and forensic analysis.
• Organic Synthesis Building Block: Acts as a chiral synthon for the construction of more complex molecular architectures in pharmaceutical and material science research.
• Carcinogenesis Mechanism Research: Utilized in *in vitro* and *in vivo* models to elucidate the mechanisms of PAH-induced carcinogenicity.
