Chemical Structure

1-(3-Bromo-phenyl)-2-(1,3-dioxolan-2-yl)-ethanone CAS 1263365-76-9 chemical structure

Description

The occurrence of 1-(3-Bromo-phenyl)-2-(1,3-dioxolan-2-yl)-ethanone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(3-Bromo-phenyl)-2-(1,3-dioxolan-2-yl)-ethanone (CAS 1263365-76-9), a certified reference material (molecular formula C11H11BrO3, MW 271.11 g/mol) for analytical method development and quality control.

The molecular framework of 1-(3-Bromo-phenyl)-2-(1,3-dioxolan-2-yl)-ethanone (C11H11BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
