5,6-dimethyl-3-(2-methylpropyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one CAS 731827-20-6

Description

CATO supplies 5,6-dimethyl-3-(2-methylpropyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 731827-20-6), a certified reference material (molecular formula C12H22N2OS2, MW 274.45 g/mol) for analytical method development and quality control.

The molecular framework of 5,6-dimethyl-3-(2-methylpropyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (C12H22N2OS2) is characterized by 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
