Description
CATO supplies tert-Butyl 5-methoxy-2-oxospiro[indoline-3,4-piperidine]-1-carboxylate (CAS 752234-64-3), a certified reference material (molecular formula C18H24N2O4, MW 332.39 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl 5-methoxy-2-oxospiro[indoline-3,4-piperidine]-1-carboxylate (C18H24N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 332.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
