Chemical Structure

3-Methylbenz[a]anthracene CAS 2498-75-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 242.31 g/mol gives 3-Methylbenz[a]anthracene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Methylbenz[a]anthracene (CAS 2498-75-1), a certified reference material (molecular formula C19H14, MW 242.31 g/mol) for analytical method development and quality control.

3-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
