Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[bis(tert-butoxycarbonyl)amino]pyrido[2,3-d]pyrimidine-7-carboxylic acid.
2-[bis(tert-butoxycarbonyl)amino]pyrido[2,3-d]pyrimidine-7-carboxylic acid (CAS 2306262-27-9), molecular formula C18H32N4O6 and molecular weight 400.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[bis(tert-butoxycarbonyl)amino]pyrido[2,3-d]pyrimidine-7-carboxylic acid (C18H32N4O6) is characterized by a steroid 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. 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.
