Frequently Asked Questions
Yes, in common usage, but trinitroglycerin is the precise chemical name for glyceryl trinitrate, while nitroglycerin is a more general term.
Due to its molecular structure with three nitro groups, which makes it highly sensitive to shock, heat, or friction, leading to rapid decomposition and explosion.
Typically as sublingual tablets, sprays, or patches to quickly relax blood vessels and relieve angina symptoms by increasing blood flow.
Storage in cool, stable environments, use of protective equipment, and adherence to strict regulations to prevent accidental detonation or exposure.
