Chemical Structure

5-Ethyl-6-methyl-4-(thiophen-2-yl)-3,4-dihydropyrimidin-2(1H)-one CAS 728004-19-1 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-Ethyl-6-methyl-4-(thiophen-2-yl)-3,4-dihydropyrimidin-2(1H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.31 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.

5-Ethyl-6-methyl-4-(thiophen-2-yl)-3,4-dihydropyrimidin-2(1H)-one (CAS 728004-19-1) is a high-purity analytical reference standard with the molecular formula C11H14N2OS and a molecular weight of 222.31 g/mol.

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.
