Cotinine-β-(4-Deoxy-4,5-didehydro)-β-D-glucuronide (CAS 146275-15-2), molecular formula C16H18N2O6 and molecular weight 334.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Cotinine-β-(4-Deoxy-4,5-didehydro)-β-D-glucuronide (C16H18N2O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
