Chemical Structure

(E)-[4-(Diethylcarbamoyl)styryl]boronic Acid Pinacol Ester CAS 933986-64-2 chemical structure

Description

The occurrence of (E)-[4-(Diethylcarbamoyl)styryl]boronic Acid Pinacol Ester is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-[4-(Diethylcarbamoyl)styryl]boronic Acid Pinacol Ester (CAS 933986-64-2), a certified reference material (molecular formula C19H28BNO3, MW 329.24 g/mol) for analytical method development and quality control.

(E)-[4-(Diethylcarbamoyl)styryl]boronic Acid Pinacol Ester (C19H28BNO3) 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.
