3-Chloro-5-ethoxy-4-propoxyphenylboronic acid CAS 2096338-74-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-5-ethoxy-4-propoxyphenylboronic acid.

3-Chloro-5-ethoxy-4-propoxyphenylboronic acid (CAS 2096338-74-6), molecular formula C11H16BClO4 and molecular weight 258.51 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H16BClO4, 3-Chloro-5-ethoxy-4-propoxyphenylboronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 3-Chloro-5-ethoxy-4-propoxyphenylboronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
