Chemical Structure
Description
The occurrence of 2-(tert-Butoxy)phenylboronic Acid Pinacol Ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(tert-Butoxy)phenylboronic Acid Pinacol Ester (CAS 2304635-80-9) is a high-purity analytical reference standard with the molecular formula C16H25BO3 and a molecular weight of 276.18 g/mol.
The molecular framework of 2-(tert-Butoxy)phenylboronic Acid Pinacol Ester (C16H25BO3) 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 its high hydrophobicity (logP), 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 2-(tert-Butoxy)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.
