2-메르캅토티아졸린

2-Mercaptothiazoline (also known as 2-Mercapto-1,3-thiazoline) is a heterocyclic sulfur-containing compound with the molecular formula C3H5NS2. It contains both a thiol (-SH) group and a thiazoline ring, giving it strong chelating, reactive, and corrosion-inhibiting properties. These features make it useful in several industrial and chemical applications.

1. Corrosion Inhibitors

One of the main applications of 2-mercaptothiazoline is in corrosion prevention, particularly for metals in acidic environments. It forms a protective film on metal surfaces—especially copper and steel—reducing oxidation and degradation in cooling systems, boilers, and oil pipelines.

2. Metal Chelating Agent

Thanks to its thiol and nitrogen atoms, it acts as a strong chelating agent for transition metals. It is used in metal treatment processes, such as electroplating, metal finishing, and in the recovery or separation of precious metals.

3. Rubber and Polymer Additive

In the rubber industry, it can serve as a vulcanization accelerator or anti-aging agent, helping improve the durability and performance of rubber compounds.

4. Intermediate in Organic Synthesis

2-Mercaptothiazoline is also used as a building block in organic synthesis, especially in the production of pesticides, pharmaceuticals, and dyes. Its reactive functional groups allow for versatile chemical modifications.

5. Biocidal Applications

Due to its sulfur-containing structure, it may exhibit antimicrobial or fungicidal properties and is sometimes evaluated for use in preservatives or antifouling agents.
