4-{[1,1'-Biphenyl]-4-carbonyl}-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (CAS 1326811-84-0), molecular formula C22H23NO4 and molecular weight 365.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-{[1,1'-Biphenyl]-4-carbonyl}-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (C22H23NO4) 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).

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.

CATO manufactures 4-{[1,1'-Biphenyl]-4-carbonyl}-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation.
