Chemical Structure
Description
3-(5-Chloro-2-phenyl-1H-indol-3-yl)propanoic acid (CAS 290832-30-3) is a high-purity analytical reference standard with the molecular formula C17H14ClNO2 and a molecular weight of 299.75 g/mol.
3-(5-Chloro-2-phenyl-1H-indol-3-yl)propanoic acid (C17H14ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
As a certified reference material (CRM), 3-(5-Chloro-2-phenyl-1H-indol-3-yl)propanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
