PTSA applications:

PTSA or pTsOH or p-Toluenesulfonic acid is white solid organic compound, that is soluble in water, alcohols, and other polar organic solvents.
It is available both in crystalline form as well as a solution and has a wide range of applications.

PTSA is widely used as a catalyst and as an intermediate in a variety of applications such as:

A catalyst in the synthesis of pharmaceuticals, pesticides, polymerization stabilizer, paint intermediates, cross linking reactions and resin curing agent. It is also a commonly used acid catalyst in organic synthesis.
As an intermediate in fine chemicals, dyestuffs & pigments.
As a curing agent in thermosetting resin systems, varnishes, acrylic resins, etc.
As a hydrotropic coupling agent & a wetting agent in esterification / condensation / acetylation / polymerization / alkylation / hydrolysis / dehydration.
It is comparable in strength to mineral acids such as sulphuric acid but is especially suitable for organic reactions where an inorganic, mineral acid could cause charring, oxidation or an unwanted chemical reaction.
