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 2-Amino-6-methyl-3-(prop-2-yn-1-yl)benzo[d]thiazol-3-ium bromide (CAS 466683-22-7), a certified reference material (molecular formula C11H11N2SBr, MW 283.19 g/mol) for analytical method development and quality control.
The molecular framework of 2-Amino-6-methyl-3-(prop-2-yn-1-yl)benzo[d]thiazol-3-ium bromide (C11H11N2SBr) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
