Thioacetic Acid (TAA) for wide range of pharmaceuticals applications


TAA (Thioacetic Acid) is a powerful donor for the synthesis of antagonists, anthypertensives, and duretics in pharmaceuticals.
It is also used to manufacture a broad spectrum antibiotics from the family of Carbanepems, and in the analysis of biological samples (PCR test).

TAA (Thioacetic Acid) can be found in D-Biotin, which is more commonly known as vitamin B7 or vitamin H, vitamin BW or coenzyme R.

Thioacetic Acid (TAA) for a wide range of Industrial applications

  • In the metallurgy industry, Thioacetic Acid (TAA) is useful to the preparation of sulfur chelates for metal scavengers.
  • In the polymers and rubber industry, TAA can be used for the preparation, by nucleophilic or radical addition, of sulfur-derived polymers with improved properties, as well as an intermediate for chain transfer agent and curing agent.
  • In the food industry, TAA can be used for the synthesis of flavor enhancer
  • Same in cosmetic industry for the synthesis of fragrance enhancer.
  • In agrochemicals, there is over 70 patents relating the use of Thioacetic Acid (TAA) to introduce the sulfur atom during the preparation of different additives.
