Nitroglycerin is a highly explosive liquid compound first synthesized by Italian chemist Ascanio Sobrero in 1847. It consists of nitrogen, oxygen, and carbon, and is known for its extreme instability and explosive power. Nitroglycerin was initially used as a treatment for angina pectoris due to its vasodilatory properties, but its medical application was limited by its unpredictable and potentially dangerous effects. Alfred Nobel, recognizing its potential as an explosive, developed a method to stabilize nitroglycerin by mixing it with an absorbent material, leading to the invention of dynamite in 1866. Despite its role in the development of explosives and its continued use in various industries, nitroglycerin remains a highly regulated substance due to its volatile nature and safety concerns.
