Pentaerythritol tetranitrate

Pentaerythritol tetranitrate (CAS 78-11-5), also known as penthrite, is a high-energy nitrate ester used across pharmaceutical and defense applications. In medicine, it functions as a vasodilator active ingredient.

In defense and aerospace, it serves as a primary explosive and detonator component. In pharmaceutical manufacturing, it is formulated into sustained-release tablets and transdermal patches for angina pectoris.

Controlled release of the active compound is critical to dosage performance. Defense and aerospace contractors use it as a base charge in detonators and as a component in flexible linear shaped charges.

It serves as a booster explosive in munitions trains and is compounded into PETN-based sheet explosives used in aerospace structural severance systems and satellite separation mechanisms.

Specialty pyrotechnic formulators incorporate it into detonating cord, where its high detonation velocity ensures reliable signal transmission across long distances for complex industrial systems.

Pentaerythritol tetranitrate is supplied as a white crystalline powder, typically wetted or desensitized with water or an inert plasticizer to meet transport and handling regulations.

Pharmaceutical-grade material is available to BP and Ph. Eur. specifications for use in medicinal formulations. Defense-grade supply follows military specifications and strict licensing.

All shipments are subject to end-user certification and export control requirements. Our technical team ensures that every batch meets the rigorous safety and purity standards required for your industry.
