Chemical Structure
Description
CATO supplies 7-Chloro-N-methyl-2-benzothiazolamine (CAS 34551-18-3), a certified reference material (molecular formula C8H7ClN2S, MW 198.67 g/mol) for analytical method development and quality control.
7-Chloro-N-methyl-2-benzothiazolamine (C8H7ClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 7-Chloro-N-methyl-2-benzothiazolamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
