Chemical Structure
Description
2-(Pyridin-2-ylsulfonyl)ethanethioamide (CAS 175276-91-2) is a high-purity analytical reference standard with the molecular formula C7H8N2O2S2 and a molecular weight of 216.28 g/mol.
2-(Pyridin-2-ylsulfonyl)ethanethioamide (C7H8N2O2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 2-(Pyridin-2-ylsulfonyl)ethanethioamide 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.
