2-mercapto-6-methyl-5-(2-methylbutyl)thieno[2,3-d]pyrimidin-4(3H)-one CAS 851116-59-1

Description

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.

2-mercapto-6-methyl-5-(2-methylbutyl)thieno[2,3-d]pyrimidin-4(3H)-one (CAS 851116-59-1), molecular formula C12H16N2OS2 and molecular weight 268.40 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H16N2OS2, 2-mercapto-6-methyl-5-(2-methylbutyl)thieno[2,3-d]pyrimidin-4(3H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
