Description
Compared with other compounds in its class, the molecular weight of 254.08 g/mol gives 5-Bromo-4-methylindole-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-4-methylindole-2-carboxylic acid (CAS 50536-58-8), molecular formula C10H8BrNO2 and molecular weight 254.08 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-4-methylindole-2-carboxylic acid (C10H8BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
