Chemical Structure
Description
As a certified reference material (CRM), 3-(Methylsulfonyl)benzenethiol 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 3-(Methylsulfonyl)benzenethiol (CAS 3814-24-2), a certified reference material (molecular formula C7H8O2S2, MW 188.27 g/mol) for analytical method development and quality control.
3-(Methylsulfonyl)benzenethiol (C7H8O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
