Chemical Structure
Description
The occurrence of 5-Bromo-4-chloro-1H-indol-3-yl β-D-galactopyranoside 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.
5-Bromo-4-chloro-1H-indol-3-yl β-D-galactopyranoside (CAS 7240-90-6), molecular formula C14H15BrClNO6 and molecular weight 408.63 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-4-chloro-1H-indol-3-yl β-D-galactopyranoside (C14H15BrClNO6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Bromo-4-chloro-1H-indol-3-yl β-D-galactopyranoside under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
