Allylthioureum

Allylthiourea is an organosulfur compound that combines a thiourea group (-CSNH₂) with an allyl group (CH₂=CH–CH₂-), giving it strong chelating, reducing, and biological activity. This makes it useful in various chemical, industrial, and research applications.

1. Heavy Metal Chelating Agent

Allylthiourea is commonly used as a chelating agent for metal ions, particularly in wastewater treatment and analytical chemistry, where it helps in the removal or detection of trace metals like mercury, copper, and lead through complexation.

2. Corrosion Inhibition

Due to its ability to form stable complexes with metal surfaces, allylthiourea serves as a corrosion inhibitor in industrial systems, such as boilers, pipelines, and cooling towers, where it protects metals from oxidative damage.

3. Biochemical Research

In microbiology and enzymology, allylthiourea is used to inhibit certain enzyme activities, such as urease, making it useful in metabolic studies and the control of nitrification in soil or wastewater research.

4. Electroplating Additive

Allylthiourea may be used as an additive in electroplating baths, especially in nickel and copper plating, where it acts as a grain refiner or brightener to improve deposit smoothness and appearance.

5. Intermediate in Organic Synthesis

With its reactive thiourea and allyl groups, it is also used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, offering structural versatility for further modification in drug development or agrochemical production.
