Chemical Structure
Description
As a certified reference material (CRM), 4-Benzoyl-8-tert-Butyl-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid 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.
CATO supplies 4-Benzoyl-8-tert-Butyl-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (CAS 1326811-69-1), a certified reference material (molecular formula C20H27NO4, MW 345.43 g/mol) for analytical method development and quality control.
The molecular framework of 4-Benzoyl-8-tert-Butyl-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (C20H27NO4) is characterized by a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
