Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Aminoethyl)-1-oxa-3-azaspiro[4.4]Nonane-2,4-dione hydrochloride.
3-(2-Aminoethyl)-1-oxa-3-azaspiro[4.4]Nonane-2,4-dione hydrochloride (CAS 1197234-16-4), molecular formula C9H14N2O3HCl and molecular weight 234.68 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(2-Aminoethyl)-1-oxa-3-azaspiro[4.4]Nonane-2,4-dione hydrochloride (C9H14N2O3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 234.68 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
