1,5-Dioxa-9-azaspiro[5.5]undecane (CAS 180-94-9) is a high-purity analytical reference standard with the molecular formula C8H15NO2 and a molecular weight of 157.21 g/mol.
1,5-Dioxa-9-azaspiro[5.5]undecane (C8H15NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
