Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(4-Bromophenyl)-2-(4-(2-fluorophenyl)piperazin-1-yl)thieno[3,2-d]pyrimidin-4(1H)-one.
CATO supplies 7-(4-Bromophenyl)-2-(4-(2-fluorophenyl)piperazin-1-yl)thieno[3,2-d]pyrimidin-4(1H)-one (CAS 1242861-55-7), a certified reference material (molecular formula C22H18BrFN4OS, MW 485.37 g/mol) for analytical method development and quality control.
Structurally, 7-(4-Bromophenyl)-2-(4-(2-fluorophenyl)piperazin-1-yl)thieno[3,2-d]pyrimidin-4(1H)-one (C22H18BrFN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 485.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.
