1-(sec-Butyl)-4-thioxo-1,3,4,5,6,7-hexahydro-2H-cyclopenta[d]pyrimidin-2-one CAS 920410-76-0

Description

1-(sec-Butyl)-4-thioxo-1,3,4,5,6,7-hexahydro-2H-cyclopenta[d]pyrimidin-2-one (CAS 920410-76-0) is a high-purity analytical reference standard with the molecular formula C11H16N2OS and a molecular weight of 224.32 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-(sec-Butyl)-4-thioxo-1,3,4,5,6,7-hexahydro-2H-cyclopenta[d]pyrimidin-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 224.32 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.
