Chemical Structure

Phosphabenzene CAS 289-68-9 chemical structure

Description

Owing to organophosphorus functionality, Phosphabenzene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.07 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).

CATO supplies Phosphabenzene (CAS 289-68-9), a certified reference material (molecular formula C5H5P, MW 96.07 g/mol) for analytical method development and quality control.

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), Phosphabenzene 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.
