Description

Sodium 3-[(4-Hydroxy-2-Butynyl)Oxy]Propanesulphonate is a specialized organosulfur compound featuring a unique propanesulphonate backbone linked via an ether bond to a hydroxybutynyl group. This molecular structure imparts valuable properties as a reactive intermediate and functional additive, particularly in advanced synthesis and formulation chemistry. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce sulfonate functionality or modify solubility profiles in target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), especially those requiring enhanced water solubility or specific ionic characteristics.
• Agrochemical Synthesis: Used in the development of modern herbicides, fungicides, and plant growth regulators where the sulfonate group can improve systemic activity and environmental profile.
• Specialty Surfactant & Detergent Formulation: Acts as a high-performance hydrotrope and coupling agent in concentrated liquid detergents, institutional cleaners, and personal care products.
• Polymer Modification: Employed as a functional monomer or additive to introduce anionic charges, improving the hydrophilicity, antistatic properties, or dyeability of synthetic polymers and coatings.
• Electroplating & Metal Treatment Additive: Functions as a brightener or leveling agent in electroplating baths, contributing to smoother, more uniform metal deposits.
• Research & Development: A valuable reagent for organic and medicinal chemists exploring new chemical entities and probing structure-activity relationships.
