4-(4-Bromophenyl)-2-(1H-indol-3-yl)-4-oxobutanoic acid (CAS 78860-79-4), molecular formula C18H14BrNO3 and molecular weight 372.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Bromophenyl)-2-(1H-indol-3-yl)-4-oxobutanoic acid (C18H14BrNO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
