Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.23 g/mol gives 9-oxo-9,10-dihydroacridine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9-oxo-9,10-dihydroacridine-2-carboxylic acid (CAS 42946-36-1) is a high-purity analytical reference standard with the molecular formula C14H9NO3 and a molecular weight of 239.23 g/mol.
The molecular framework of 9-oxo-9,10-dihydroacridine-2-carboxylic acid (C14H9NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 9-oxo-9,10-dihydroacridine-2-carboxylic acid 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.
