Chemical Structure
Description
tert-Butyl 2-oxospiro[indoline-3,3'-pyrrolidine]-1'-carboxylate (CAS 205383-87-5) is a high-purity analytical reference standard with the molecular formula C16H20N2O3 and a molecular weight of 288.34 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, tert-Butyl 2-oxospiro[indoline-3,3'-pyrrolidine]-1'-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-oxospiro[indoline-3,3'-pyrrolidine]-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.
