Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Methylbenz[a]anthracene-d3.
7-Methylbenz[a]anthracene-d3 (CAS 1795033-70-3), molecular formula C19H11D3 and molecular weight 245.33 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Methylbenz[a]anthracene-d3 (C19H11D3) contains deuterium isotope labeling, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 245.33 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.
