Meaning and Definition
A specific inorganic salt with the chemical formula NH₄OCN, historically famous for its conversion to urea.
A white crystalline compound known primarily for its role in Wöhler's 1828 experiment, which demonstrated the synthesis of an organic compound (urea) from an inorganic precursor, challenging vitalism in chemistry.

Common Mistakes When Using “ammonium cyanate”

- Confusing it with 'ammonium cyanide', a different, more violently toxic compound.
FAQ
Frequently Asked Questions
It is classified as an inorganic salt, despite being the precursor in the synthesis of the organic compound urea.
It demonstrated for the first time that a compound known only from living organisms (urea) could be made from inorganic materials, challenging the dominant theory of vitalism which stated that organic compounds required a 'vital force'.
Like many cyanate salts, it should be handled with care as it can release toxic cyanide compounds under certain conditions (e.g., in acidic environments). It is not as immediately toxic as cyanides, but is still hazardous.
Its primary use is in educational and historical contexts. It is not a common reagent in modern synthetic laboratories, as more efficient routes to urea and other compounds have been developed.
