Nitroglycerin (NG, alternative spelling nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid.

Lore & Background
Sobrero initially called it 'pyroglycerin' and warned against its use as an explosive. Nobel founded Alfred Nobel and Company in Germany and built an isolated factory in the Krümmel hills near Hamburg, which was destroyed twice.
Reader's Guide
Nitroglycerin's significance lies in its dual role as a powerful explosive and a life-saving medication. As the first practical explosive stronger than black powder, it enabled major engineering projects such as the Summit Tunnel for the First transcontinental railroad in North America. Its instability, however, caused numerous devastating accidents, leading to legal restrictions and the invention of dynamite. Its legacy includes shaping modern explosives, propellants (e.g., double-based smokeless powder), and cardiovascular therapy.

Frequently Asked Questions
Who is Nitroglycerin?
Nitroglycerin is a heavy, nearly transparent oily liquid that sits at the crossroads of explosives and cardiology. Its formal chemical identity is 1,2,3-trinitroxypropane, though fans and professionals alike often just call it "nitro" or "NG."
What are Nitroglycerin's powers/role?
On one end of the spectrum, it serves as the shock-sensitive core ingredient that goes into dynamite and other blasting agents. On the other, it acts as a vasodilator that relaxes blood-vessel walls, making it a go-to treatment for angina and certain forms of heart failure.
How does Nitroglycerin's story end?
As a chemical compound, Nitroglycerin has no narrative arc, but its practical "story" is still unfolding. It remains a standard component in controlled demolition and mining while simultaneously being prescribed in sublingual tablet form to millions of cardiac patients worldwide.
Why is Nitroglycerin important?
It is one of the rare substances that is simultaneously a devastating explosive and a life-saving drug, giving it a uniquely dual role in both industry and medicine. Its discovery reshaped construction and mining in the nineteenth century, and its pharmacological use continues to manage chest pain and circulatory crises today.
