Tri-P-Cresyl Phosphate CAS 78-32-0 chemical structure

Description

As a certified reference material (CRM), Tri-P-Cresyl Phosphate 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.

Tri-P-Cresyl Phosphate (CAS 78-32-0), molecular formula C21H21O4P and molecular weight 368.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, Tri-P-Cresyl Phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
