Chemical Structure

Phenyl di(p-tolyl) phosphate CAS 34909-69-8 chemical structure

Description

CATO supplies Phenyl di(p-tolyl) phosphate (CAS 34909-69-8), a certified reference material (molecular formula C20H19O4P, MW 354.34 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, Phenyl di(p-tolyl) phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.34 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.

CATO manufactures Phenyl di(p-tolyl) phosphate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
