Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Iodoisothiazole.
CATO supplies 5-Iodoisothiazole (CAS 49602-30-4), a certified reference material (molecular formula C3H2INS, MW 211.02 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, iodine substitution, 5-Iodoisothiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.02 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Iodoisothiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
