Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)-N-(2-morpholinoethyl)piperidine-3-carboxamide.
1-(4-Hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)-N-(2-morpholinoethyl)piperidine-3-carboxamide (CAS 1242864-59-0), molecular formula C24H29N5O3S and molecular weight 467.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(4-Hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)-N-(2-morpholinoethyl)piperidine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 467.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
