Description

Bis(o-Tolyl)Phosphine CAS NO 29949-64-2 is a versatile organophosphorus compound featuring two ortho-tolyl groups bonded to a central phosphorus atom. This structure makes it a valuable ligand in transition metal catalysis and a key intermediate in the synthesis of specialty chemicals. It is primarily sought after by manufacturers and R&D teams in the pharmaceutical, agrochemical, and advanced materials sectors for developing new catalysts and fine chemical processes.

Application

• As a ligand in homogeneous catalysis for cross-coupling reactions (e.g., Suzuki, Heck).
• Key intermediate in the synthesis of photoinitiators and other specialty phosphines.
• Precursor for flame retardants and polymer additives.
• Used in organic light-emitting diode (OLED) material research.
• Building block for pharmaceutical active ingredients (APIs) and agrochemicals.
• Component in lubricant and fuel additive formulations.

Quality Control

Our Bis(o-Tolyl)Phosphine is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and 31P NMR analysis, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, containers should be kept sealed and only opened in a controlled environment.
