3-Cyclopentyl-1,2,3,5,6,7-hexahydro-2-thioxo-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one CAS 731827-01-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Cyclopentyl-1,2,3,5,6,7-hexahydro-2-thioxo-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one.

3-Cyclopentyl-1,2,3,5,6,7-hexahydro-2-thioxo-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one (CAS 731827-01-3), molecular formula C14H16N2OS2 and molecular weight 292.42 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, 3-Cyclopentyl-1,2,3,5,6,7-hexahydro-2-thioxo-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
