Chemical Structure

(2-hydroxy-4-methylphenyl)boronic acid CAS 259209-25-1 chemical structure

Description

The occurrence of (2-hydroxy-4-methylphenyl)boronic 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.

(2-hydroxy-4-methylphenyl)boronic acid (CAS 259209-25-1) is a high-purity analytical reference standard with the molecular formula C7H15BO3 and a molecular weight of 158.00 g/mol.

Structurally, (2-hydroxy-4-methylphenyl)boronic acid (C7H15BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 158.00 g/mol, it falls into the medium-molecular-weight range.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
