Chemical Structure
Description
4-(2-Naphthyl)phenylboronic Acid Pinacol Ester (CAS 1092390-02-7) is a high-purity analytical reference standard with the molecular formula C22H23BO2 and a molecular weight of 330.23 g/mol.
Based on its molecular formula C22H23BO2, 4-(2-Naphthyl)phenylboronic Acid Pinacol Ester contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 4-(2-Naphthyl)phenylboronic Acid Pinacol Ester 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.
