Chemical Structure
Description
4-(2-Phenyl-1H-benzimidazol-1-yl)phenylboronic Acid (contains varying amounts of Anhydride) (CAS 867044-33-5), molecular formula C19H15BN2O2 and molecular weight 314.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-Phenyl-1H-benzimidazol-1-yl)phenylboronic Acid (contains varying amounts of Anhydride) (C19H15BN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(2-Phenyl-1H-benzimidazol-1-yl)phenylboronic Acid (contains varying amounts of Anhydride) 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.
