Chemical Structure
Description
3-(2-Carboxyethyl)-4-chloro-1H-indole-2-carboxylic acid (C12H10ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-(2-Carboxyethyl)-4-chloro-1H-indole-2-carboxylic acid (CAS 130798-49-1), molecular formula C12H10ClNO4 and molecular weight 267.67 g/mol, is a CATO reference standard with documented purity and traceability.
