Chemical Structure
Description
1'-Benzyl 1-(tert-butyl) 5-fluorospiro[indoline-3,4'-piperidine]-1,1'-dicarboxylate (C25H29FN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
1'-Benzyl 1-(tert-butyl) 5-fluorospiro[indoline-3,4'-piperidine]-1,1'-dicarboxylate (CAS 1201649-36-6), molecular formula C25H29FN2O4 and molecular weight 440.51 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
