Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-bromo-1,3-benzothiazole-2-thiol.
CATO supplies 7-bromo-1,3-benzothiazole-2-thiol (CAS 908355-83-9), a certified reference material (molecular formula C7H4BrNS2, MW 246.15 g/mol) for analytical method development and quality control.
7-bromo-1,3-benzothiazole-2-thiol (C7H4BrNS2) contains a nitrile group, sulfur-containing functionality, bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 7-bromo-1,3-benzothiazole-2-thiol 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.
