3-Oxa-9-azaspiro[5.5]undecane oxalate CAS 1956321-79-1

Description

The occurrence of 3-Oxa-9-azaspiro[5.5]undecane oxalate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Oxa-9-azaspiro[5.5]undecane oxalate (CAS 1956321-79-1), molecular formula C9H17NOC2H2O4 and molecular weight 245.27 g/mol, is a CATO reference standard with documented purity and traceability.

3-Oxa-9-azaspiro[5.5]undecane oxalate (C9H17NOC2H2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
