Chemical Structure

(E)-(3-(3-Ethoxy-3-oxoprop-1-en-1-yl)phenyl)boronic acid CAS 913835-51-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 220.03 g/mol gives (E)-(3-(3-Ethoxy-3-oxoprop-1-en-1-yl)phenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-(3-(3-Ethoxy-3-oxoprop-1-en-1-yl)phenyl)boronic acid (CAS 913835-51-5) is a high-purity analytical reference standard with the molecular formula C11H13BO4 and a molecular weight of 220.03 g/mol.

The molecular framework of (E)-(3-(3-Ethoxy-3-oxoprop-1-en-1-yl)phenyl)boronic acid (C11H13BO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

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.
