Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-one.
6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-one (CAS 30459-51-9), molecular formula C9H8ClNOS and molecular weight 213.68 g/mol, is a CATO reference standard with documented purity and traceability.
6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-one (C9H8ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-one 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.
