Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-Cyclopentyl-2-((2-ethoxy-4-(4-hydroxypiperidin-1-yl)phenyl)amino)-5-methyl-8,9-dihydro-5H-pyrimido[4,5-b][1,4]diazepin-6(7H)-one, >98% (HPLC).
9-Cyclopentyl-2-((2-ethoxy-4-(4-hydroxypiperidin-1-yl)phenyl)amino)-5-methyl-8,9-dihydro-5H-pyrimido[4,5-b][1,4]diazepin-6(7H)-one, >98% (HPLC) (CAS 1228817-38-6), molecular formula C26H36N6O3 and molecular weight 480.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-Cyclopentyl-2-((2-ethoxy-4-(4-hydroxypiperidin-1-yl)phenyl)amino)-5-methyl-8,9-dihydro-5H-pyrimido[4,5-b][1,4]diazepin-6(7H)-one, >98% (HPLC) (C26H36N6O3) 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.
