Description

Compared with other compounds in its class, the molecular weight of 311.40 g/mol gives 7-Phenyl-2-(piperidin-1-yl)thieno[3,2-d]pyrimidin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Phenyl-2-(piperidin-1-yl)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 1708251-33-5) is a high-purity analytical reference standard with the molecular formula C17H17N3OS and a molecular weight of 311.40 g/mol.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 7-Phenyl-2-(piperidin-1-yl)thieno[3,2-d]pyrimidin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.40 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.

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.

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.
