Chemical Structure
Description
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 supplies Tert-butyl 3-amino-1-oxa-9-azaspiro[5.5]Undecane-9-carboxylate (CAS 2408645-69-0), a certified reference material (molecular formula C14H26N2O3, MW 270.37 g/mol) for analytical method development and quality control.
Structurally, Tert-butyl 3-amino-1-oxa-9-azaspiro[5.5]Undecane-9-carboxylate (C14H26N2O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 270.37 g/mol, it falls into the medium-molecular-weight range. 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).
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.
