Chemical Structure
Description
CATO supplies 9-(4-Phenylphenyl)carbazole-3-boronic acid (CAS 1028648-22-7), a certified reference material (molecular formula C24H18BNO2, MW 363.22 g/mol) for analytical method development and quality control.
9-(4-Phenylphenyl)carbazole-3-boronic acid (C24H18BNO2) 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 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.
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.
