Chemical Structure
Description
The occurrence of 5-Bromoindoline-6-carboxylic acid hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Bromoindoline-6-carboxylic acid hydrochloride (CAS 2137804-02-3), a certified reference material (molecular formula C9H8BrNO2HCl, MW 278.53 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H8BrNO2HCl, 5-Bromoindoline-6-carboxylic acid hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 278.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
