(2,5-Difluoro-1,4-phenylene)diboronic acid CAS 1256358-83-4

Description

Compared with other compounds in its class, the molecular weight of 201.73 g/mol gives (2,5-Difluoro-1,4-phenylene)diboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2,5-Difluoro-1,4-phenylene)diboronic acid (CAS 1256358-83-4), molecular formula C6H6B2F2O4 and molecular weight 201.73 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (2,5-Difluoro-1,4-phenylene)diboronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), (2,5-Difluoro-1,4-phenylene)diboronic 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.
