Chemical Structure

4-(1-Hydroxyethyl)phenylboronic Acid CAS 518336-20-4 chemical structure

Description

The occurrence of 4-(1-Hydroxyethyl)phenylboronic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(1-Hydroxyethyl)phenylboronic Acid (CAS 518336-20-4), molecular formula C8H11BO3 and molecular weight 165.98 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H11BO3, 4-(1-Hydroxyethyl)phenylboronic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 165.98 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-(1-Hydroxyethyl)phenylboronic 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.
