Chemical Structure

Tetraphenylborate CAS 4358-26-3 chemical structure

Description

As a certified reference material (CRM), Tetraphenylborate 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.

Tetraphenylborate (CAS 4358-26-3), molecular formula C24H20B and molecular weight 319.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a polycyclic aromatic system, Tetraphenylborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.23 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.
