Description

Methylphenylchlorophosphine is a versatile organophosphorus reagent widely used in chemical synthesis. Its primary value lies in its role as a key building block for the preparation of phosphine ligands, catalysts, and other phosphorus-containing compounds. This product is essential for research and development laboratories, as well as industrial-scale production in the pharmaceutical, agrochemical, and specialty chemical sectors. Methylphenylchlorophosphine CAS NO 15849-86-2 is a critical intermediate for scientists and engineers developing advanced materials and active ingredients.

Application

• Phosphine Ligand Synthesis: A crucial precursor for creating chiral and achiral phosphine ligands used in asymmetric catalysis and cross-coupling reactions (e.g., Suzuki, Heck).
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates that incorporate phosphorus.
• Agrochemical Production: Used to manufacture herbicides, insecticides, and plant growth regulators that contain phosphine or phosphonate groups.
• Flame Retardant & Polymer Additives: Serves as an intermediate for phosphorus-based flame retardants and stabilizers for plastics and polymers.
• Material Science: Key building block for creating phosphonium salts, ylides, and other functional materials with specific electronic or surface properties.
• Organic Synthesis Reagent: Used directly in reactions to introduce the methylphenylphosphine moiety or as a chlorinating agent for phosphorus compounds.

Quality Control

Our Methylphenylchlorophosphine is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment. We are committed to meeting the stringent requirements of research and industrial applications.

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. Due to its highly volatile and easily oxidized nature, it is recommended to store at temperatures between 2°C and 8°C for extended stability. Keep away from strong acids, bases, and oxidizing agents.
