Chemical Structure
Description
4-Methyl-1-oxa-4,9-diazaspiro[5.5]Undecan-3-one hydrochloride (C9H16N2O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-Methyl-1-oxa-4,9-diazaspiro[5.5]Undecan-3-one hydrochloride (CAS 1609403-58-8) is a high-purity analytical reference standard with the molecular formula C9H16N2O2HCl and a molecular weight of 220.70 g/mol.
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.
