Chemical Structure
Description
The molecular framework of (4-(Cyclopropylsulfonyl)phenyl)boronic acid (C9H11BO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(4-(Cyclopropylsulfonyl)phenyl)boronic acid (CAS 1217501-07-9) is a high-purity analytical reference standard with the molecular formula C9H11BO4S and a molecular weight of 226.06 g/mol.
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.
