Chemical Structure

tert-Butyl 5-bromo-2-oxospiro[indoline-3,4’-piperidine]-1’-carboxylate CAS 873779-30-7 chemical structure

Description

As a certified reference material (CRM), tert-Butyl 5-bromo-2-oxospiro[indoline-3,4’-piperidine]-1’-carboxylate 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.

tert-Butyl 5-bromo-2-oxospiro[indoline-3,4’-piperidine]-1’-carboxylate (CAS 873779-30-7) is a high-purity analytical reference standard with the molecular formula C17H21BrN2O3 and a molecular weight of 381.26 g/mol.

tert-Butyl 5-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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
