Light Yellow Powder Benzo[a]pyrene CAS 50-32-8

Products Description

What is Light yellow powder Benzo[a]pyrene CAS 50-32-8 ?

The compound corresponding to CAS 50-32-8 is Benzo[a]pyrene, with a molecular formula of C₂₀H₁₂ and a molecular weight of 252.31 g/mol. It is a polycyclic aromatic hydrocarbon composed of five angularly fused benzene rings, and its unique molecular structure makes it a representative polycyclic aromatic hydrocarbon (PAHs) compound.

Benzo[a]pyrene appears as a light yellow crystalline powder at room temperature, exhibiting a melting point of 177–180°C, boiling point of 495°C, and density of 1.35 g/cm³. It is readily soluble in organic solvents such as benzene, toluene, and chloroform, with slight solubility in ethanol.

Uses

In carcinogenic mechanism research, Benzo[a]pyrene is used in animal experiments (e.g., skin application or oral administration in mice) to study the interaction between its metabolites (e.g., BPDE) and DNA, revealing the molecular pathways of gene mutation and tumorigenesis. As a drug development model, it screens compounds with anti-mutagenic or anti-cancer activity, such as evaluating the inhibitory effect of natural products (e.g., tea polyphenols) on their carcinogenicity. For toxicology standards, it serves as a positive control in toxicity tests to assess the potential carcinogenic risk of new chemicals.
