Description
Compared with other compounds in its class, the molecular weight of 318.37 g/mol gives tert-Butyl 5-hydroxy-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyl 5-hydroxy-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate (CAS 1823272-51-0) is a high-purity analytical reference standard with the molecular formula C17H22N2O4 and a molecular weight of 318.37 g/mol.
The molecular framework of tert-Butyl 5-hydroxy-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate (C17H22N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures tert-Butyl 5-hydroxy-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
