Tert-butyl 7-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate (CAS 1779125-91-5), molecular formula C17H21BrN2O3 and molecular weight 381.26 g/mol, is a CATO reference standard with documented purity and traceability.
Tert-butyl 7-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate (C17H21BrN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
