4-(Isothiazol-5-yl)phenol CAS 68535-60-4 chemical structure

Description

As a certified reference material (CRM), 4-(Isothiazol-5-yl)phenol 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 4-(Isothiazol-5-yl)phenol (CAS 68535-60-4), a certified reference material (molecular formula C9H7NOS, MW 177.22 g/mol) for analytical method development and quality control.

4-(Isothiazol-5-yl)phenol (C9H7NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
