Chemical Structure

2-(4-Bromo-3-indolyl)-2-oxoacetic Acid CAS 1126693-15-9 chemical structure

Description

2-(4-Bromo-3-indolyl)-2-oxoacetic Acid (CAS 1126693-15-9) is a high-purity analytical reference standard with the molecular formula C10H6BrNO3 and a molecular weight of 268.06 g/mol.

2-(4-Bromo-3-indolyl)-2-oxoacetic Acid (C10H6BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
