Chemical Structure
Description
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 supplies 3-Amino-6-bromo-7-hydroxy-4-azaindole (CAS 1260381-63-2), a certified reference material (molecular formula C7H6BrN3O, MW 228.05 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 3-Amino-6-bromo-7-hydroxy-4-azaindole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
