Chemical Structure

Methyl[tris(2-methylphenyl)phosphine]gold CAS 110981-37-8 chemical structure

Description

As a certified reference material (CRM), Methyl[tris(2-methylphenyl)phosphine]gold 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.

CATO supplies Methyl[tris(2-methylphenyl)phosphine]gold (CAS 110981-37-8), a certified reference material (molecular formula C22H24AuP, MW 516.37 g/mol) for analytical method development and quality control.

The molecular framework of Methyl[tris(2-methylphenyl)phosphine]gold (C22H24AuP) is characterized by organophosphorus functionality, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
