Chrysene is a polycyclic aromatic hydrocarbon (PAH) composed of four fused benzene rings, primarily used in scientific research, environmental studies, and as a reference standard for analytical chemistry due to its presence in combustion byproducts and fossil fuels. It also serves as a starting material in organic synthesis and is used in manufacturing certain dyes and wood preservatives. It has a CAS number of 218-01-9, a molecular formula of C18H12, and a molecular weight of 228.29 g/mol. Store at ambient conditions, but handle with caution—it carries a **Danger** signal word for its potential toxicity and carcinogenicity. Molekula supplies Chrysene from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

This substance is available from Molekula on enquiry. Full specification, Safety Data Sheet and Certificate of Analysis documentation are provided with your quotation once our team confirms the grade and pack size you need.
