Pentaerythritol tetranitrate (PETN), also known as PENT, pentyl, PENTA (ПЕНТА, primarily in Russian), TEN (tetraeritrit nitrate), corpent, or penthrite (or, rarely and primarily in German, as nitropenta), is an explosive material.

PETN, a highly explosive organic compound belonging to the same chemical family as nitroglycerin and nitrocellulose. PETN has the chemical formula C5H8N4O12. It is prepared by reacting pentaerythritol (C5H12O4), an alcohol traditionally used in paints and varnishes, with nitric acid (HNO2).

PETN stands amongst the most potent explosives in existence, with a Relative Effectiveness Factor (REF) of 1.66, making it exponentially more powerful than TNT. Unlike some other explosives,...

In contrast to other long-acting nitrates, PETN induces tolerance- free vasodilation in humans and was reported to prevent endothelial dysfunction as well as atherogenesis in cholesterol- fed rabbits. ... The active PETN metabolite PETriN stimulates protein expression of the antioxidant defense protein heme oxygenase-1 (HO-1).

2023年7月31日 · Pentaerythritol tetranitrate or PETN is an explosive material, widely used in military applications, mainly due to its good stability and general performances. It is a nitrated organic compound, with the chemical formula C 5 H 8 N 4 O 12 .

Pentaerythritol tetranitrate (PETN), also known as PENT, PENTA, TEN, corpent, penthrite (or — rarely and primarily in German — as nitropenta) is one of the most powerful high explosives known. It has a relative effectiveness factor (R.E. factor) of 1.66. [1] PETN can be used as a plastic explosive.

Pentaerythritol tetranitrate (PETN), CASRN 78-11-5, belongs to the class of compounds known as organic nitrates. It is used mainly as a demolition explosive and in the manufacture of detonating fuses and blasting caps (O’Neil, 2013; Lewis, 2007).
