Description

Allyl-Phosphinic Acid CAS NO 66899-05-6 is a specialized organophosphorus compound featuring a reactive allyl group directly bonded to a phosphinic acid moiety. This unique structure makes it a valuable intermediate for synthesizing advanced materials and fine chemicals, offering a versatile handle for further functionalization. It is primarily sought by research and development chemists and industrial manufacturers in the agrochemical, pharmaceutical, and polymer sectors.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those targeting neurological pathways.
• Agrochemical Synthesis: Used as a precursor for developing new herbicides, fungicides, and plant growth regulators with enhanced efficacy.
• Flame Retardant Precursor: Acts as a starting material for creating phosphorus-based flame retardants, which are increasingly important for plastics, textiles, and electronics.
• Ligand and Catalyst Development: Employed in organometallic chemistry to create novel ligands for metal catalysts used in asymmetric synthesis and polymerization.
• Polymer Modification: Incorporated into polymer backbones or as a cross-linking agent to impart specific properties like adhesion, thermal stability, or flame resistance.
• Research & Development: A crucial reagent in academic and industrial R&D for exploring new reactions in organophosphorus chemistry and material science.

Quality Control

Our Allyl-Phosphinic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
