7-(4-Ethoxyphenyl)-4-methyl-2-(methylthio)-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine CAS 338416-18-5

Description

7-(4-Ethoxyphenyl)-4-methyl-2-(methylthio)-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine (CAS 338416-18-5), molecular formula C16H19N3OS and molecular weight 301.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 7-(4-Ethoxyphenyl)-4-methyl-2-(methylthio)-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.41 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.
