Chemical Structure
Description
CATO supplies 6-Methylbenzo[a]pyrene (CAS 2381-39-7), a certified reference material (molecular formula C21H14, MW 266.34 g/mol) for analytical method development and quality control.
Structurally, 6-Methylbenzo[a]pyrene (C21H14) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 266.34 g/mol, it falls into the medium-molecular-weight range. 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.
