Chemical Structure

4-(tert-Butoxy)phenylboronic Acid Pinacol Ester CAS 938063-51-5 chemical structure

Description

The occurrence of 4-(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.

CATO supplies 4-(tert-Butoxy)phenylboronic Acid Pinacol Ester (CAS 938063-51-5), a certified reference material (molecular formula C16H25BO3, MW 276.18 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-(tert-Butoxy)phenylboronic Acid Pinacol Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(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.
