Chemical Structure

(3-(Diphenylamino)phenyl)boronic acid CAS 943899-12-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 289.14 g/mol gives (3-(Diphenylamino)phenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-(Diphenylamino)phenyl)boronic acid (CAS 943899-12-5), molecular formula C18H16BNO2 and molecular weight 289.14 g/mol, is a CATO reference standard with documented purity and traceability.

(3-(Diphenylamino)phenyl)boronic acid (C18H16BNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
