2-(Allylthio)-7,9-dimethyl-4-(m-tolyloxy)pyrido[3',2':4,5]thieno[3,2-d]pyrimidine CAS 478065-71-3 chemical structure

Description

The occurrence of 2-(Allylthio)-7,9-dimethyl-4-(m-tolyloxy)pyrido[3',2':4,5]thieno[3,2-d]pyrimidine is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Allylthio)-7,9-dimethyl-4-(m-tolyloxy)pyrido[3',2':4,5]thieno[3,2-d]pyrimidine (CAS 478065-71-3), molecular formula C21H19N3OS2 and molecular weight 393.53 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(Allylthio)-7,9-dimethyl-4-(m-tolyloxy)pyrido[3',2':4,5]thieno[3,2-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 393.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
