2-Methyl-2-thiopseudourea Sulfate丨CAS 867-44-7

2-Methyl-2-thiopseudourea sulfate is a valuable reagent and intermediate used primarily in pharmaceutical, agrochemical, and organic synthesis. Its thiourea functionality enables it to act as a building block for the synthesis of guanidine, amidine, and heterocyclic compounds, which are important scaffolds in drug discovery and medicinal chemistry. It is frequently employed in the preparation of bioactive molecules, including antiviral, anticancer, and enzyme-inhibiting agents, as well as in agrochemical development for herbicides and pesticides. Additionally, it is used in chemical research for nucleophilic addition reactions, thiocarbonyl chemistry, and the construction of sulfur-containing heterocycles, providing a versatile route for designing novel compounds with tailored biological and chemical properties.

The benefits of 2-Methyl-2-thiopseudourea sulfate are derived from its chemical reactivity, stability, and solubility. The thiourea moiety offers high nucleophilicity and reactivity toward carbonyl and electrophilic centers, allowing efficient synthesis of guanidines, amidines, and heterocycles. Its sulfate salt form enhances stability, ease of handling, and solubility in aqueous and polar organic solvents, facilitating multi-step reactions without decomposition. The presence of the methyl group provides additional steric and electronic control, which can improve selectivity in downstream transformations. These properties make it suitable for both laboratory research and scalable industrial synthesis, enabling reproducible and high-yield production of functionalized intermediates.
