Chemical Structure
Description
The molecular framework of 4-{14,14-dimethyl-12-oxo-2,9-diazatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3(8),4,6-tetraen-10-yl}benzoic acid (C22H22N2O3) is characterized by a steroid 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).
4-{14,14-dimethyl-12-oxo-2,9-diazatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3(8),4,6-tetraen-10-yl}benzoic acid (CAS 1022356-50-8), molecular formula C22H22N2O3 and molecular weight 362.42 g/mol, is a CATO reference standard with documented purity and traceability.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
