Chemical Structure
Description
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.
1-Oxa-9-azaspiro[5.5]undecan-4-ol hydrochloride (CAS 399033-70-6), molecular formula C9H17NO2HCl and molecular weight 207.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Oxa-9-azaspiro[5.5]undecan-4-ol hydrochloride (C9H17NO2HCl) 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 manufactures 1-Oxa-9-azaspiro[5.5]undecan-4-ol hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
