What does PTSA stand for?

PTSA is the abbreviation of p-Toluenesulfonic Acid, a toluene derivative with sulfonic acid functional group (-SO3H). It is also applied in catalysis, polymerization and pharmaceuticals because it is a strong acid and is soluble in organic solvents.

At AAOL India, we produce our PTSA to meet the most rigorous quality standards to guarantee the purity, stability and performance of the product for its use in industry. We are therefore a leading supplier of PTSA chemical solutions for industries all over the world.

PTSA Structure, Molecular Weight & Chemical Properties

The PTSA structure has a benzene ring with a methyl (-CH3) group and a sulfonic acid functional group(-SO3H) which increases the reactivity of the molecule. The PTSA molecular weight (PTSA mol wt) is somewhat different based on the form:

  • PTSA Anhydrous: 172.20 g/mol
  • PTSA Monohydrate: 190.22 g/mol

Other key chemical properties of PTSA include:

  • PTSA CAS No.: 104-15-4 (Anhydrous), 6192-52-5 (Monohydrate)
  • PTSA Boiling Point: Approximately 140°C (decomposes upon heating)
  • Solubility: Highly soluble in water, alcohols, and polar organic solvents

 At AAOL India, we offer tailored PTSA formulations to achieve the best results in several applications. Our team of professionals ensures that the products are consistent and we are your go-to partner for high-quality chemicals.

Industrial Applications of PTSA: Where It’s Used

At AAOL India, we supply PTSA chemical solutions to various industries and guarantee high purity and effectiveness. The main PTSA chemical uses are: 

  • Catalyst in Organic Synthesis: PTSA is employed as an acid catalyst in esterification, polymerization and hydrolysis reactions.
  • Pharmaceuticals: An integral part of drug development and production of active pharmaceutical ingredients (APIs).
  • Resins & Polymers: Serves as a catalyst in the formation of phenolic and amino resins.
  • Electronics & Plastics: Improves the resistance to decay of photoresists and thermosetting plastics.
  • Dyes & Pigments: Employed in the manufacturing of dyes to enhance the durability and colorfastness.
  • Textile Industry: Used in the dyeing process to increase the affinity and brightness of the dyes.
  • Agriculture: PTSA derivatives are employed in the manufacture of different agrochemicals and plant growth regulators.

Our PTSA monohydrate and anhydrous solutions are developed to increase effectiveness and productivity in these industries. AAOL India continues to lead in providing tailored PTSA solutions to address the increasing needs.

PTSA Reagent & Its Role in Chemical Reactions

 As a PTSA reagent, p-Toluenesulfonic Acid is less volatile and more stable than mineral acids and, therefore, is a better alternative. It is mainly used for:

  • Estherification and Transesterification: For converting carboxylic acids to esters.
  • Acidic Cleavage of Protecting Groups: Involved in the deprotection of silyl ethers and acetals.
  • Polymerization Catalyst: For the production of stable polymers and resins.
  • Adhesives & Coatings: Improves durability and bonding strength in industrial adhesives.

At AAOL India, we provide specific customized PTSA solutions to fit the specific needs of industries across the world. We provide for consistent quality and performance, thus making our PTSA chemical solutions very dependable and effective.
