Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1246818-35-8 9-Hydroxy Benzopyrene-d11.
1246818-35-8 9-Hydroxy Benzopyrene-d11 (CAS 1246818-35-8), molecular formula C20HD11O and molecular weight 279.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1246818-35-8 9-Hydroxy Benzopyrene-d11 (C20HD11O) is characterized by deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
