Description

9-Hydroxybenzo(A)Pyrene is a hydroxylated derivative of the well-studied polycyclic aromatic hydrocarbon (PAH), benzo(a)pyrene. This compound is of significant value as a key reference standard and analytical standard in environmental and toxicological research. It is primarily required by research institutions, analytical laboratories, and chemical manufacturers engaged in the study of PAH metabolism, environmental monitoring, and the development of detection methods.

Application

• Analytical Reference Standard: Used as a primary standard for the calibration and validation of analytical instruments like HPLC, GC-MS, and LC-MS in the quantification of PAHs and their metabolites.
• Environmental Research: Employed in studies monitoring soil, water, and air pollution to understand the transformation and degradation pathways of carcinogenic PAHs.
• Metabolic and Toxicological Studies: Serves as a critical metabolite standard in research investigating the biotransformation, DNA adduct formation, and carcinogenic mechanisms of benzo(a)pyrene.
• Pharmaceutical and Biomedical Research: Utilized in biochemical assays to study enzyme activity (e.g., cytochrome P450) involved in xenobiotic metabolism.
• Quality Control: Acts as a known compound in the quality assurance processes for laboratories testing industrial products or environmental samples for PAH contamination.
