Chemical Structure

Copper tris[tris(2-methylphenyl)phosphine]- CAS 91019-20-4 chemical structure

Description

Copper tris[tris(2-methylphenyl)phosphine]- (CAS 91019-20-4), molecular formula C21H21PCu and molecular weight 367.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Copper tris[tris(2-methylphenyl)phosphine]- (C21H21PCu) 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.

CATO manufactures Copper tris[tris(2-methylphenyl)phosphine]- 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.
