Chemical Structure

Ethyl 3-Oxotetrahydrothiopyran-2-carboxylate CAS 58509-73-2 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.

CATO supplies Ethyl 3-Oxotetrahydrothiopyran-2-carboxylate (CAS 58509-73-2), a certified reference material (molecular formula C8H12O3S, MW 188.24 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 3-Oxotetrahydrothiopyran-2-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Ethyl 3-Oxotetrahydrothiopyran-2-carboxylate 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.
