Description

3-(Tris(Hydroxymethyl)Phosphonio)Propion CAS NO 15931-64-3 is a specialized organophosphorus compound featuring a phosphonium cation with hydroxymethyl substituents. This unique structure makes it a valuable intermediate and functional additive in advanced material synthesis and specialty chemical manufacturing. It is primarily sought after by R&D chemists and production engineers in the pharmaceutical, polymer, and fine chemical industries for applications requiring phosphorus-based functionality and water solubility.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates, particularly those requiring phosphonium-based moieties for targeted activity or as prodrug components.
• Polymer Additive & Crosslinking Agent: Acts as a flame retardant precursor, a curing agent for epoxy resins, or a modifier to enhance polymer thermal stability and surface properties.
• Ligand & Catalyst Precursor: Serves as a starting material for creating phosphine-based ligands used in homogeneous catalysis, such as in cross-coupling reactions.
• Bioconjugation & Protein Modification: Utilized in biochemical research for modifying peptides, proteins, or other biomolecules due to its reactive phosphonium group and hydrophilic character.
• Surface Treatment & Corrosion Inhibition: Applied in formulations for metal surface treatments or as a component in corrosion inhibitor packages for industrial fluids.
• Textile & Paper Chemical: Functions as a durable press resin modifier, a wet-strength agent for paper, or an antistatic agent in synthetic fibers.
