Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Oxa-7-azaspiro[4.4]nonane hemioxalate (CAS 2828444-89-7), a certified reference material (molecular formula C7H13NOC2H2O4, MW 217.22 g/mol) for analytical method development and quality control.
The molecular framework of 2-Oxa-7-azaspiro[4.4]nonane hemioxalate (C7H13NOC2H2O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 2-Oxa-7-azaspiro[4.4]nonane hemioxalate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
