3-({2,5-diphenylthieno[2,3-d]pyrimidin-4-yl}amino)-1λ4-thiolan-1-one CAS 1394648-11-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-({2,5-diphenylthieno[2,3-d]pyrimidin-4-yl}amino)-1λ4-thiolan-1-one.

3-({2,5-diphenylthieno[2,3-d]pyrimidin-4-yl}amino)-1λ4-thiolan-1-one (CAS 1394648-11-3), molecular formula C22H19N3OS2 and molecular weight 405.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-({2,5-diphenylthieno[2,3-d]pyrimidin-4-yl}amino)-1λ4-thiolan-1-one (C22H19N3OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
