Chemical Structure

3-Butoxy-4-chloro-2-fluorophenylboronic acid CAS 1256346-25-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Butoxy-4-chloro-2-fluorophenylboronic acid.

CATO supplies 3-Butoxy-4-chloro-2-fluorophenylboronic acid (CAS 1256346-25-4), a certified reference material (molecular formula C10H13BClFO3, MW 246.47 g/mol) for analytical method development and quality control.

Structurally, 3-Butoxy-4-chloro-2-fluorophenylboronic acid (C10H13BClFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 246.47 g/mol, it falls into the medium-molecular-weight range. 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.
