1-Hexylthiourea is primarily utilized in research and industrial applications due to its ability to act as a corrosion inhibitor. It is effective in protecting metals, particularly in acidic environments, by forming a protective layer on the metal surface, thereby reducing the rate of corrosion. This makes it valuable in industries where metal preservation is critical, such as in pipelines, storage tanks, and machinery.

In addition to its corrosion-inhibiting properties, 1-Hexylthiourea is also employed in chemical synthesis as a reagent or intermediate. It can be used in the preparation of other organic compounds, particularly those involving sulfur-containing functional groups. Its role in synthesis is often linked to its ability to act as a nucleophile or to participate in complexation reactions.

Furthermore, it has been studied for its potential use in biological and biochemical research, particularly in studies related to enzyme inhibition or as a component in analytical chemistry for detecting specific metal ions. Its unique chemical structure allows it to interact with various biological and chemical systems, making it a versatile compound in experimental settings.
