3-(Difluoromethoxy)-4-fluorophenylboronic acid CAS 958451-70-2

Description

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

3-(Difluoromethoxy)-4-fluorophenylboronic acid (CAS 958451-70-2), molecular formula C7H6BF3O3 and molecular weight 205.93 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H6BF3O3, 3-(Difluoromethoxy)-4-fluorophenylboronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-(Difluoromethoxy)-4-fluorophenylboronic 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.
