Description

N-(4-cyanophenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide (CAS 1105207-70-2), molecular formula C21H14N4O2S and molecular weight 386.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(4-cyanophenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide (C21H14N4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 386.43 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
