Chemical Structure

(3-Fluoro-4-(methylthio)phenyl)boronic acid CAS 221030-80-4 chemical structure

Description

The occurrence of (3-Fluoro-4-(methylthio)phenyl)boronic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3-Fluoro-4-(methylthio)phenyl)boronic acid (CAS 221030-80-4) is a high-purity analytical reference standard with the molecular formula C7H8BFO2S and a molecular weight of 186.01 g/mol.

Structurally, (3-Fluoro-4-(methylthio)phenyl)boronic acid (C7H8BFO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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 186.01 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.

As a certified reference material (CRM), (3-Fluoro-4-(methylthio)phenyl)boronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
