Cyanide vs. Isocyanide — What's the Difference?
By Tayyaba Rehman — Published on November 7, 2023
Cyanide, containing a C≡N- group, is a lethal ion/substance. Isocyanide, with a N≡C group, is used in organic syntheses.

Key Differences
Cyanide is commonly recognized in the realm of chemical compounds due to its notorious toxic properties. Its functional group, which is composed of a carbon triple-bonded to a nitrogen (C≡N-), plays a critical role in its characteristics. On the other hand, Isocyanide, not as commonly encountered outside of organic chemistry contexts, features a structure in which the nitrogen is triple-bonded to the carbon (N≡C).
Cyanide is a compound that has been widely recognized for its historical usage in mining to extract gold and other precious metals from ore. Simultaneously, Isocyanides are more niche and are mostly utilized in specialized organic synthesis due to their unique reactivity, making them beneficial for constructing complex organic molecules.
Notably, Cyanides are potent inhibitors of cellular respiration, binding to a critical enzyme and thereby preventing the utilization of oxygen by cells. Conversely, Isocyanides, while having a certain degree of toxicity, are not renowned for this characteristic and play a more significant role in synthetic chemistry.
In various industries, Cyanide compounds find usage due to their ability to react with and bind metals, a property that has also led to their application in electroplating. Isocyanides, given their particular reactivity in organic synthesis, find usage in the creation of various organic compounds, including some pharmaceuticals.
In terms of regulatory attention, Cyanides, due to their toxicity, are subject to numerous regulations globally, ensuring they are handled with utmost care to prevent accidental exposure. Isocyanides, while regulated, are not under the same stringent control due to their lower toxicity and specific usage in chemical syntheses.
