trans-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one CAS 2489613-05-8

Description

The occurrence of trans-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

trans-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one (CAS 2489613-05-8), molecular formula C7H10OS and molecular weight 142.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, trans-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one (C7H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 142.22 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
