Description

4-Methylbenzo[A]Pyrene is a high-purity, polycyclic aromatic hydrocarbon (PAH) derivative, specifically a methylated analog of benzo[a]pyrene. This compound is of significant interest in research and analytical chemistry as a critical reference standard and a model compound for studying the metabolism and environmental impact of methylated PAHs. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions focused on toxicology, carcinogenesis, and environmental monitoring.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments like HPLC, GC-MS, and LC-MS in the quantification of PAHs in complex matrices.
• Environmental Analysis: Serves as a key analyte in testing for PAH contamination in soil, water, air particulates, and industrial waste to meet regulatory compliance (e.g., EPA methods).
• Toxicological Research: Employed in biochemical and pharmacological studies to investigate the metabolic pathways, DNA adduct formation, and carcinogenic mechanisms of methylated polycyclic aromatic compounds.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for the separation and detection of complex PAH mixtures.
• Quality Control: Used as an internal standard or spike in quality control protocols for laboratories analyzing PAHs in food, consumer products, and industrial materials.
