Chemical Structure
Description
The molecular framework of 7-chloro-4-methoxy-1,3-benzothiazol-2-amine (C8H15ClN2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
7-chloro-4-methoxy-1,3-benzothiazol-2-amine (CAS 67618-12-6) is a high-purity analytical reference standard with the molecular formula C8H15ClN2OS and a molecular weight of 222.74 g/mol.
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-4-methoxy-1,3-benzothiazol-2-amine 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.
