5-(3,4-dimethylphenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one CAS 851116-23-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(3,4-dimethylphenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one.

CATO supplies 5-(3,4-dimethylphenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 851116-23-9), a certified reference material (molecular formula C14H24N2OS2, MW 300.48 g/mol) for analytical method development and quality control.

The molecular framework of 5-(3,4-dimethylphenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (C14H24N2OS2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
