Methyl hydrazine sulfate(CAT: R049002) is an inorganic salt composed of methylhydrazine (CH₃NHNH₂) and sulfuric acid, forming a stable, crystalline solid with enhanced handling and storage properties compared to the free base. It serves primarily as a reagent and intermediate in the synthesis of pharmaceuticals, agrochemicals, and heterocyclic compounds, particularly in reactions involving hydrazone formation, reductive amination, and cyclization. The sulfate salt form reduces volatility and flammability, offering improved safety in laboratory settings. Due to its potential toxicity and reactivity, it should be handled with appropriate precautions.
