Usage
Vitamin B5 key intermediate: Used in the synthesis of D-panthenol, D-calcium pantothenate, etc., it is a precursor substance for coenzyme A biosynthesis, ensuring human energy metabolism and physiological functions.
As a chain extender or crosslinking agent, it introduces hydroxyl and carboxyl groups, improving the mechanical strength, weather resistance, and adhesive properties of PU, and is used in water-based polyurethane dispersions, coatings, and adhesives.
It is used to synthesize non-ionic surfactants for textile auxiliaries and emulsifiers, and can also be used to prepare high-performance synthetic lubricants suitable for extreme working conditions.
As a chelating agent, it forms stable complexes with metal ions, and is used in metal corrosion inhibitors and electroplating additives, improving the corrosion resistance and bonding strength of metal surfaces.
