3-[(3-Methylphenyl)methyl]-3H,4H-thieno[2,3-d]pyrimidin-4-one CAS 338777-28-9

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.

CATO supplies 3-[(3-Methylphenyl)methyl]-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 338777-28-9), a certified reference material (molecular formula C14H12N2OS, MW 256.32 g/mol) for analytical method development and quality control.

Structurally, 3-[(3-Methylphenyl)methyl]-3H,4H-thieno[2,3-d]pyrimidin-4-one (C14H12N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 256.32 g/mol, it falls into the medium-molecular-weight range. 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.
