Description

1-Dichlorophosphoryl-3-Methyl-Buta-1,2-Diene is a highly reactive organophosphorus compound characterized by its dichlorophosphoryl group and conjugated diene system. This unique structure makes it a valuable versatile building block for synthesizing complex phosphorus-containing molecules. It is primarily sought after by pharmaceutical, agrochemical, and specialty chemical R&D departments for the development of novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel organophosphorus drug candidates, including potential enzyme inhibitors.
• Agrochemical Synthesis: Building block for creating advanced pesticides, herbicides, and plant growth regulators with new modes of action.
• Ligand and Catalyst Development: Used to prepare specialized phosphine and phosphonite ligands for homogeneous catalysis in fine chemical production.
• Polymer Modification: Serves as a functional monomer or cross-linking agent for introducing phosphorus groups into polymer backbones to impart flame retardancy or other properties.
• Material Science Research: Employed in the development of advanced materials, such as phosphorus-doped ceramics or novel electronic materials.
• Chemical Synthesis Reagent: Acts as a phosphorylating and chlorinating agent in complex organic transformations for research and pilot-scale production.

Quality Control

Our 1-Dichlorophosphoryl-3-Methyl-Buta-1,2-Diene is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR, GC, and HPLC analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its highly volatile and hygroscopic nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from strong bases and oxidizing agents.
