Chemical Structure

10-Methylbenz[a]pyrene CAS 63104-32-5 chemical structure

Description

10-Methylbenz[a]pyrene (CAS 63104-32-5), molecular formula C21H14 and molecular weight 266.34 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C21H14, 10-Methylbenz[a]pyrene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures 10-Methylbenz[a]pyrene 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.
