Chemical Structure
Description
The molecular framework of tert-Butyl 5-oxa-2,8-diazaspiro[3.5]nonane-8-carboxylate hydrochloride (C11H20N2O3HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies tert-Butyl 5-oxa-2,8-diazaspiro[3.5]nonane-8-carboxylate hydrochloride (CAS 2241130-99-2), a certified reference material (molecular formula C11H20N2O3HCl, MW 264.75 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
