Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
trans-Dichlorobis(methyldiphenylphosphine)palladium(II) (CAS 26973-01-3), molecular formula C26H26Cl2P2Pd and molecular weight 577.76 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, trans-Dichlorobis(methyldiphenylphosphine)palladium(II) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 577.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures trans-Dichlorobis(methyldiphenylphosphine)palladium(II) 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.
