Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
Dichloro(3,4,5,6-tetrapropyl-2H-pyran-2-ylidene)bis(triphenylphosphine)platinum (CAS 105430-62-4) is a high-purity analytical reference standard with the molecular formula C53H58Cl2OP2Pt and a molecular weight of 1038.96 g/mol.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Dichloro(3,4,5,6-tetrapropyl-2H-pyran-2-ylidene)bis(triphenylphosphine)platinum is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1038.96 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.
