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 Benzothiazole, 4-methoxy- (7CI,8CI,9CI).
CATO supplies Benzothiazole, 4-methoxy- (7CI,8CI,9CI) (CAS 3048-46-2), a certified reference material (molecular formula C8H7NOS, MW 165.21 g/mol) for analytical method development and quality control.
The molecular framework of Benzothiazole, 4-methoxy- (7CI,8CI,9CI) (C8H7NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Benzothiazole, 4-methoxy- (7CI,8CI,9CI) 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.
