Description

Phosphoric Acid-(n-Phenylsulfonylamide)Dichloride is a specialized organophosphorus reagent primarily used as a key intermediate in advanced organic synthesis. This compound matters for its role in constructing complex molecular architectures, particularly in the development of pharmaceuticals and agrochemicals. Industries requiring high-purity synthetic building blocks, such as pharmaceutical R&D, fine chemical manufacturing, and agrochemical production, are the primary users of this material.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing sulfonamide or phosphorus-based functional groups.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators that require specific phosphorus-sulfur linkages.
• Ligand Precursor: Acts as a precursor for the development of specialized ligands used in catalysis and metal complexation processes.
• Polymer Modification: Employed in the synthesis of flame-retardant additives or specialty monomers for high-performance polymers.
• Chemical Research: A valuable reagent in academic and industrial research laboratories for exploring new reaction pathways and creating novel chemical entities.
• Peptide Mimetic Synthesis: Utilized in the construction of peptide analogs and bioisosteres where the phosphoramidate moiety is incorporated.

Quality Control

Our Phosphoric Acid-(n-Phenylsulfonylamide)Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption and decomposition. Keep away from incompatible materials such as strong bases and oxidizing agents.
