Description

Isopropenylphosphonic Dichloride is a highly reactive organophosphorus compound primarily used as a key synthetic intermediate. Its value lies in its ability to introduce the versatile isopropenylphosphonyl group into target molecules, enabling the creation of novel materials and functional chemicals. This product is essential for researchers and manufacturers in the agrochemical, pharmaceutical, and specialty polymer industries seeking to develop advanced active ingredients and flame-retardant additives.

Application

• Agrochemical Intermediate: A critical building block for synthesizing novel herbicides, insecticides, and plant growth regulators with enhanced efficacy.
• Pharmaceutical Synthesis: Used in the preparation of phosphonate-based prodrugs and bioactive molecules, including potential antiviral and anticancer agents.
• Flame Retardant Precursor: Serves as a key monomer for producing advanced, reactive organophosphorus flame retardants for engineering plastics and textiles.
• Ligand and Catalyst Development: Employed in the synthesis of specialized phosphonate ligands for metal catalysis and coordination chemistry.
• Surface Modification Agent: Used to create phosphonic acid-based self-assembled monolayers (SAMs) on metal oxides for corrosion inhibition and surface functionalization.
• Specialty Polymer Monomer: Incorporated into polymers to impart specific properties such as adhesion promotion, hydrophilicity, or chelating ability.

Quality Control

Our Isopropenylphosphonic Dichloride is produced under stringent quality control protocols to ensure batch-to-batch consistency and high purity for demanding synthetic applications. Every lot is analyzed using advanced techniques including GC, NMR, and titration to verify identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
