Description

Benzo(A)Pyrene, 7,8-Dimethyl- is a dimethylated derivative of the well-studied polycyclic aromatic hydrocarbon (PAH), benzo[a]pyrene. This specific structural analog is a critical reference standard and research chemical used extensively in environmental, toxicological, and analytical chemistry studies. It is primarily required by research institutions, analytical testing laboratories, and chemical manufacturers engaged in the study of PAH metabolism, carcinogenicity, and environmental monitoring.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments (HPLC, GC-MS) in environmental and food safety testing.
• Toxicological Research: Serves as a key compound in studies investigating the metabolic pathways, DNA adduct formation, and carcinogenic mechanisms of polycyclic aromatic hydrocarbons.
• Environmental Monitoring: Used in method development and quality control for the analysis of PAH contaminants in soil, water, air particulate matter, and industrial emissions.
• Biochemical Studies: Employed in research focusing on enzyme interactions (e.g., cytochrome P450) and the biological impact of specific PAH derivatives.
• Material Science Research: Can be used in studies related to combustion chemistry, soot formation, and the characterization of complex hydrocarbon mixtures.
