Chemical Structure

(3-Methoxy-2-methylphenyl)boronic acid CAS 1313617-76-3 chemical structure

Description

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.

(3-Methoxy-2-methylphenyl)boronic acid (CAS 1313617-76-3), molecular formula C8H11BO3 and molecular weight 165.98 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3-Methoxy-2-methylphenyl)boronic acid (C8H11BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 165.98 g/mol, it falls into the medium-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
