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.
Tert-butyl (2-oxa-7-azaspiro[4.4]Nonan-9-yl)carbamate (CAS 2411073-23-7), molecular formula C12H22N2O3 and molecular weight 242.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tert-butyl (2-oxa-7-azaspiro[4.4]Nonan-9-yl)carbamate (C12H22N2O3) contains an amino-acid-derived structure, an amide 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 242.31 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.
