Sodium cyanate is primarily used in organic synthesis as a reagent for the production of various organic compounds. It is often employed in the synthesis of urea derivatives, which are important in the manufacture of pharmaceuticals, agrochemicals, and plastics. In the pharmaceutical industry, it serves as a key intermediate in the production of certain drugs, including anticonvulsants and antihypertensive agents. Additionally, sodium cyanate is used in the preparation of herbicides and pesticides, contributing to agricultural productivity by controlling weed and pest populations. It also finds application in the production of specialty chemicals, such as dyes and pigments, where it acts as a precursor or intermediate. In some cases, it is utilized in research laboratories for studying reaction mechanisms and developing new synthetic pathways.
