4-(4-Bromophenyl)-2-(1-methyl-1H-indol-3-yl)-4-oxobutanoic acid (CAS 937604-70-1), molecular formula C19H16BrNO3 and molecular weight 386.24 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-Bromophenyl)-2-(1-methyl-1H-indol-3-yl)-4-oxobutanoic acid (C19H16BrNO3) contains a steroid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
