Medical Definition of NITROGLYCERIN
: a heavy oily explosive poisonous liquid C3H5N3O9 used chiefly in making dynamites and in medicine as a vasodilator (as in angina pectoris)—called also trinitrin, trinitroglycerin; see nitro-dur, nitrostat
Organic compound, powerful explosive and ingredient of most forms of dynamite. It is a colourless, oily, somewhat toxic liquid with a sweet, burning taste. Its safe use as a blasting explosive became possible after Alfred P. Nobel developed dynamite in the 1860s with an inert porous material (moderator) such as charcoal or diatomaceous earth. Nitroglycerin is also used in a mixture in rocket propellants. In medicine, it is used to dilate blood vessels, especially to ease angina pectoris.
