Description

The occurrence of 4,5-Dihydro-6H-cyclopenta[d]thiazol-6-one is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,5-Dihydro-6H-cyclopenta[d]thiazol-6-one (CAS 1211522-56-3), molecular formula C6H5NOS and molecular weight 139.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4,5-Dihydro-6H-cyclopenta[d]thiazol-6-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.17 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).
