2-Mercapto-7-methyl-3-(3-methyl-butyl)-5,6,7,8-tetrahydro-3H-benzo[4,5]thieno[2,3-d]pyrimidin-4-one CAS 571919-27-2

Description

Compared with other compounds in its class, the molecular weight of 322.49 g/mol gives 2-Mercapto-7-methyl-3-(3-methyl-butyl)-5,6,7,8-tetrahydro-3H-benzo[4,5]thieno[2,3-d]pyrimidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Mercapto-7-methyl-3-(3-methyl-butyl)-5,6,7,8-tetrahydro-3H-benzo[4,5]thieno[2,3-d]pyrimidin-4-one (CAS 571919-27-2), a certified reference material (molecular formula C16H22N2OS2, MW 322.49 g/mol) for analytical method development and quality control.

2-Mercapto-7-methyl-3-(3-methyl-butyl)-5,6,7,8-tetrahydro-3H-benzo[4,5]thieno[2,3-d]pyrimidin-4-one (C16H22N2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
