2-Chloro-5-fluoro-3-methylphenylboronic acid CAS 2121511-44-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-5-fluoro-3-methylphenylboronic acid.

2-Chloro-5-fluoro-3-methylphenylboronic acid (CAS 2121511-44-0), molecular formula C7H7BClFO2 and molecular weight 188.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Chloro-5-fluoro-3-methylphenylboronic acid (C7H7BClFO2) 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 188.39 g/mol, it falls into the medium-molecular-weight range. 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.
