Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 7-Chloro-4-fluorobenzo[d]thiazol-2-amine (CAS 872365-04-3), a certified reference material (molecular formula C7H4ClFN2S, MW 202.64 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-4-fluorobenzo[d]thiazol-2-amine (C7H4ClFN2S) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. 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.
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.
