Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 163.97 g/mol gives (3-Formyl-2-methylphenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3-Formyl-2-methylphenyl)boronic acid (CAS 631909-10-9), a certified reference material (molecular formula C8H9BO3, MW 163.97 g/mol) for analytical method development and quality control.
The molecular framework of (3-Formyl-2-methylphenyl)boronic acid (C8H9BO3) is characterized by 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).
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.
CATO manufactures (3-Formyl-2-methylphenyl)boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
