N,N'-Diisopropylcarbamimidothioic acid(CAS: 2986-17-6)

N,N'-Diisopropylcarbamimidothioic acid is a crystalline compound with a molecular weight of approximately 215.34 g/mol. It has a melting point of 165-167°C and is only slightly soluble in water. The compound is reactive towards nucleophiles and can form adducts with them. It is a colorless to slightly yellow solid with a pungent odor.

N,N'-Diisopropylcarbamimidothioic acid can be synthesized by reacting diisopropylamine with carbon disulfide followed by treatment with hydroxylamine. The reaction involves the formation of an imidodicarbamate intermediate, which then undergoes a rearrangement to form the final product. The process typically yields 80-85% purity with good selectivity.

N,N'-Diisopropylcarbamimidothioic acid is used in the synthesis of various pharmaceuticals, including antiviral agents and immunosuppressants. It also finds applications in the polymer industry as a cross-linking agent and in the production of sensors for detecting volatile organic compounds. Additionally, it is used in the semiconductor industry as a component in etching solutions.

When handling N,N'-Diisopropylcarbamimidothioic acid, it is crucial to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The compound should be handled in a well-ventilated area or a fume hood due to its pungent odor and potential reactivity. Spills should be neutralized with a suitable base before cleaning up. Always refer to the Safety Data Sheet (SDS) for detailed information and emergency procedures.
