Pentaerythritol tetranitrate facts for kids
Pentaerythritol tetranitrate (often called PETN) is a very powerful chemical. It's known by other names too, like PENT or penthrite. PETN is special because it has two very different uses. It can be a strong explosive, but it can also be used as a drug to help people with certain heart problems.

What is PETN?
PETN is a type of chemical compound called a nitrate ester. It's made from a substance called pentaerythritol and nitric acid. When it's made, it looks like a white, crystalline powder. This powder is very stable, which means it doesn't easily react or explode on its own.
PETN as an Explosive
PETN is considered one of the most powerful high explosives known. This means it can release a lot of energy very quickly. It's often used in things like detonators, which are small devices that start bigger explosions. It can also be part of plastic explosives, which are soft and moldable.
How Explosives Work
Explosives like PETN work by changing very quickly from a solid into a gas. This change happens so fast that it creates a huge amount of pressure. This pressure is what causes the explosive force. PETN is very efficient at this, which is why it's so powerful.
PETN as a Medicine
Even though it's a powerful explosive, PETN also has an important use in medicine. It can be used to treat certain heart conditions. One common condition it helps with is called angina pectoris. Angina causes chest pain because the heart isn't getting enough blood.
Helping the Heart
When used as a medicine, PETN helps to widen blood vessels. This process is called vasodilation. By making the blood vessels wider, more blood can flow through them. This means the heart gets more oxygen and nutrients, which can relieve chest pain. PETN is one of the most common substances used for this purpose.
History of PETN
PETN was first made in Germany in 1894 by a scientist named Bernhard Tollens. It was discovered while he was doing experiments with chemicals. Over time, scientists learned about its powerful properties. Its use as both an explosive and a medicine developed later.
Safety Information
Because PETN is a powerful chemical, it must be handled very carefully. When used in medicine, it is given in very small, controlled doses. This ensures it helps the body without causing any harm. Its use as an explosive is also highly regulated to ensure safety.
