Chemical Structure
Description
Tert-butyl 6-bromospiro[indene-1,4'-piperidine]-1'-carboxylate (C18H22BrNO2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Tert-butyl 6-bromospiro[indene-1,4'-piperidine]-1'-carboxylate (CAS 158628-80-9) is a high-purity analytical reference standard with the molecular formula C18H22BrNO2 and a molecular weight of 364.28 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Tert-butyl 6-bromospiro[indene-1,4'-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.
