Description

1-Methylbenzo(A)Pyrene is a methylated derivative of the well-known polycyclic aromatic hydrocarbon (PAH), benzo(a)pyrene. This compound is of significant interest in research and analytical chemistry, particularly for use as a reference standard and metabolite standard in environmental and toxicological studies. It is essential for laboratories focused on PAH analysis, carcinogenicity research, and the development of analytical methods for complex hydrocarbon mixtures.

Application

• Analytical Reference Standard: Used for the calibration of instruments (GC, HPLC, GC-MS) and as a qualitative/quantitative standard in the analysis of environmental samples, food, and industrial materials for PAH contamination.
• Toxicological Research: Serves as a critical metabolite or intermediate in studies investigating the metabolic activation, DNA adduct formation, and carcinogenic mechanisms of polycyclic aromatic hydrocarbons.
• Environmental Monitoring: Employed in method development and validation for detecting and quantifying trace levels of alkylated PAHs in soil, water, air particulate matter, and sediment.
• Product Safety Testing: Used as a benchmark compound in the quality control of materials like fuels, oils, and consumer products to ensure compliance with safety regulations regarding PAH content.
• Chemical Synthesis: Acts as a building block or precursor in organic synthesis for creating more complex PAH derivatives for specialized research applications.
• Forensic Analysis: Aids in source identification and fingerprinting of complex hydrocarbon mixtures in forensic and petrochemical investigations.
