NitroGlycerin Molecule Model. 3 Sizes.

Nitroglycerin, also known as nitroglycerine, trinitroglycerin, trinitroglycerine, or nitro, is more correctly known as glyceryl trinitrate or more formally: 1,2,3-trinitroxypropane. It is a heavy, colorless, oily, explosive liquid.
Since the 1860s, nitroglycerin has been used as an active ingredient in the manufacture of explosives, mostly dynamite, and as such it is employed in the construction, demolition, and mining industries. Similarly, since the 1880s, it has been used by the military as an active ingredient, and a gelatinizer for nitrocellulose, in some solid propellants, such as Cordite and Ballistite.

Nitroglycerin is also a major component in double-based smokeless gunpowders used by reloaders. Combined with nitrocellulose, there are hundreds of (powder) combinations used by rifle, pistol, and shotgun reloaders. For over 130 years, nitroglycerin has been used medically as a potent vasodilator to treat heart conditions, such as angina pectoris and chronic heart failure.
