Tetrabutylammonium bromide (TBAB) might be utilized as a part of the liquid condition in the below procedures:

·        Synthesis of isophthalic acid

·        Synthesis of alkyl-secondary pyrroles without impetus and natural solvent

·        Synthesis of dithioacetals against acetals through transthioacetalisation in a dissolvable free condition

·        Synthesis of polyamides through the polymerization of diisocyanates as well as terephthalic corrosive

·        Enzyme the expansion of thiols to bound alkenes

·        Poly (vinyl chloride) Dehydrochlorination

·        Utilized with phosphorus pentoxide for greener deoxybromination

·        Prepare for making Halogenated Heteroaryl Compounds
