Description
CATO manufactures (2,5-Dimethyl-1,4-phenylene)diboronic 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.
(2,5-Dimethyl-1,4-phenylene)diboronic acid (CAS 90085-60-2) is a high-purity analytical reference standard with the molecular formula C8H12B2O4 and a molecular weight of 193.80 g/mol.
The molecular framework of (2,5-Dimethyl-1,4-phenylene)diboronic acid (C8H12B2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
