Chemical Structure

2H-Thiopyran-3(4H)-one 1,1-dioxide CAS 104482-59-9 chemical structure

Description

As a certified reference material (CRM), 2H-Thiopyran-3(4H)-one 1,1-dioxide 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.

CATO supplies 2H-Thiopyran-3(4H)-one 1,1-dioxide (CAS 104482-59-9), a certified reference material (molecular formula C5H6O3S, MW 146.16 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H6O3S, 2H-Thiopyran-3(4H)-one 1,1-dioxide contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 146.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
