5-Bromo-3-pentyloxyphenylboronic acid CAS 2121512-33-0

Description

Compared with other compounds in its class, the molecular weight of 286.96 g/mol gives 5-Bromo-3-pentyloxyphenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Bromo-3-pentyloxyphenylboronic acid (CAS 2121512-33-0), a certified reference material (molecular formula C11H16BBrO3, MW 286.96 g/mol) for analytical method development and quality control.

The molecular framework of 5-Bromo-3-pentyloxyphenylboronic acid (C11H16BBrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
