Application

Sodium tetraborate decahydrate can be used as a catalyst in the:

Regioselective thiolysis of 1,2-epoxides by using thiols to synthesize β-hydroxy sulfides.
Hetero-Michael addition of thiols with electron-deficient olefins to synthesize corresponding β-adducts.
Solvent-free Biginelli reaction to synthesize 3,4-dihydropyrimidin-2(1H)-ones.

It can also be used as an additive to prepare polypyrrole-borax composites with high dielectric properties.
