Chemical Structure

7-Bromo-5-chloro-1H-indole-3-carbaldehyde CAS 1100217-75-1 chemical structure

Description

The occurrence of 7-Bromo-5-chloro-1H-indole-3-carbaldehyde 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 7-Bromo-5-chloro-1H-indole-3-carbaldehyde (CAS 1100217-75-1), a certified reference material (molecular formula C9H5BrClNO, MW 258.50 g/mol) for analytical method development and quality control.

The molecular framework of 7-Bromo-5-chloro-1H-indole-3-carbaldehyde (C9H5BrClNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
