7-Phenyl-3-(3-(trifluoromethyl)benzyl)thieno[3,2-d]pyrimidin-4(3H)-one CAS 1105224-80-3

Description

7-Phenyl-3-(3-(trifluoromethyl)benzyl)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 1105224-80-3), molecular formula C20H13F3N2OS and molecular weight 386.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Phenyl-3-(3-(trifluoromethyl)benzyl)thieno[3,2-d]pyrimidin-4(3H)-one (C20H13F3N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
