Chemical Structure

Tetracresyl bisphenol A bisphosphate CAS 93981-32-9 chemical structure

Description

Tetracresyl bisphenol A bisphosphate (C43H42O8P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Tetracresyl bisphenol A bisphosphate (CAS 93981-32-9), molecular formula C43H42O8P2 and molecular weight 748.74 g/mol, is a CATO reference standard with documented purity and traceability.

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), Tetracresyl bisphenol A bisphosphate 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.
