N-(4-butylphenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide CAS 1105235-44-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-butylphenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide.

N-(4-butylphenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide (CAS 1105235-44-6) is a high-purity analytical reference standard with the molecular formula C24H23N3O2S and a molecular weight of 417.52 g/mol.

N-(4-butylphenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide (C24H23N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
