Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2-methylthiazolo[4,5-b]pyridine.
CATO supplies 5-Chloro-2-methylthiazolo[4,5-b]pyridine (CAS 118872-73-4), a certified reference material (molecular formula C7H5ClN2S, MW 184.65 g/mol) for analytical method development and quality control.
5-Chloro-2-methylthiazolo[4,5-b]pyridine (C7H5ClN2S) contains a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system. 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), 5-Chloro-2-methylthiazolo[4,5-b]pyridine 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.
