cis-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one CAS 118597-91-4

Description

The occurrence of cis-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.

cis-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one (CAS 118597-91-4), molecular formula C7H10OS and molecular weight 142.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of cis-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one (C7H10OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), cis-1,3,3a,4,6,6a-hexahydrocyclopenta[c]thiophen-5-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
