Description

Diphenyl-o-tolylphosphine (CAS No. 17511-60-3) is a high-purity organophosphorus compound with the molecular formula C19H17P and IUPAC name (2-methylphenyl)-diphenylphosphane. This air-sensitive phosphine ligand is widely utilized in coordination chemistry and catalysis due to its electron-donating properties and steric bulk. Our product is rigorously tested to ensure ??98% purity (GC) and is supplied as a crystalline solid under inert atmosphere packaging to maintain stability.

Key applications include use as a precursor in transition metal complexes for cross-coupling reactions (Suzuki, Heck) and asymmetric hydrogenation catalysts. The ortho-tolyl group provides enhanced steric hindrance compared to simple triphenylphosphine, making it valuable for controlling selectivity in metal-mediated transformations. Proper handling under nitrogen/argon is recommended due to sensitivity to oxidation.

Available in research quantities (1g to 100g) with optional custom packaging. SDS and Certificate of Analysis provided with all orders.
