异硫氰酸酯是一类含有R-N=C=S结构通式的化合物,是一类重要的有机合成中间体,在农药上有广泛的应用,可作为杀菌剂、杀虫剂、除草剂的中间体。新型的取代硫脲类化合物因具有高效低毒的特点,在杀虫、杀螨、除草等方面有很好的市场应用前景。异硫氰酸酯是合成双取代基硫脲的中间体。 Isothiocyanates are a class of compounds containing the general structural formula RN = C = S and are an important class of organic synthesis intermediates. They are widely used in pesticides and can be used as fungicides, insecticides, herbicides Intermediate. Because of its high efficiency and low toxicity, the new substituted thiourea compounds have good market prospects in insecticidal, acaricidal and weeding control. Isothiocyanates are intermediates for the synthesis of bis-substituted thioureas.
