Chemical Structure
Description
tert-Butyl 7-methoxy-3,4-dihydro-2H-spiro[isoquinoline-1,4'-piperidine]-1'-carboxylate (CAS 1160247-66-4) is a high-purity analytical reference standard with the molecular formula C19H28N2O3 and a molecular weight of 332.44 g/mol.
tert-Butyl 7-methoxy-3,4-dihydro-2H-spiro[isoquinoline-1,4'-piperidine]-1'-carboxylate (C19H28N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
