2840-29-1 3-Amino-4-bromo-benzoic acid 3-Amino-4-bromobenzoic acid A20114 CAS 2840-29-1

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.

2840-29-1 3-Amino-4-bromo-benzoic acid 3-Amino-4-bromobenzoic acid A20114 (CAS 2840-29-1), molecular formula C7H12BrNO2 and molecular weight 222.08 g/mol, is a CATO reference standard with documented purity and traceability.

2840-29-1 3-Amino-4-bromo-benzoic acid 3-Amino-4-bromobenzoic acid A20114 (C7H12BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

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.
