Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(7-(3-Methoxyphenyl)-4-oxo-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)-N-(pyridin-2-ylmethyl)piperidine-3-carboxamide.
1-(7-(3-Methoxyphenyl)-4-oxo-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)-N-(pyridin-2-ylmethyl)piperidine-3-carboxamide (CAS 1243044-26-9), molecular formula C25H25N5O3S and molecular weight 475.56 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-(7-(3-Methoxyphenyl)-4-oxo-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)-N-(pyridin-2-ylmethyl)piperidine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1-(7-(3-Methoxyphenyl)-4-oxo-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)-N-(pyridin-2-ylmethyl)piperidine-3-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
