Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-chloro-2-methyl-1,3-benzothiazol-4-amine (CAS 855463-87-5), a certified reference material (molecular formula C8H7ClN2S, MW 198.67 g/mol) for analytical method development and quality control.
The molecular framework of 5-chloro-2-methyl-1,3-benzothiazol-4-amine (C8H7ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 5-chloro-2-methyl-1,3-benzothiazol-4-amine 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.
