4-Methylbenz[a]anthracene CAS 316-49-4 chemical structure

Description

CATO manufactures 4-Methylbenz[a]anthracene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

4-Methylbenz[a]anthracene (CAS 316-49-4) is a high-purity analytical reference standard with the molecular formula C19H14 and a molecular weight of 242.31 g/mol.

4-Methylbenz[a]anthracene (C19H14) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
