Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Dimethyl 2,2'-((3R,4S)-tetrahydrothiophene-3,4-diyl)diacetate (CAS 118597-90-3), molecular formula C10H16O4S and molecular weight 232.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dimethyl 2,2'-((3R,4S)-tetrahydrothiophene-3,4-diyl)diacetate (C10H16O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
As a certified reference material (CRM), Dimethyl 2,2'-((3R,4S)-tetrahydrothiophene-3,4-diyl)diacetate 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.
