A wide range of pharmaceuticals applications


TAA is seen as a powerful donor for the synthesis of pharmaceuticals, the product can be used as an antagonist, an anthypertensive, as a duretic. It is also used in a broad spectrum antibiotics from the family of Carbanepems, and in the analysis of biological samples (PCR test).

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

A wide range of Industrial applications

In the metallurgy industry, TAA is useful 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.
TAA is also described as an intermediate for chain transfer agent  and curing agent.

In the food industry, TAA is used as a flavor enhancer. Sulfur-containing are also used in the cosmetic industry as a fragrance enhancer.

In agrochemicals, there is over 70 patents relating the use of TAA to introduce the sulfur atom during the preparation of different additives.
