2,4,6-Trinitrotoluene solution is primarily used in military and industrial applications as a high explosive. It is commonly employed in the production of munitions, such as bombs, shells, and grenades, due to its stability and powerful detonation properties. The solution is also utilized in demolition activities for controlled explosions in construction and mining industries. Additionally, it serves as a key component in the manufacture of explosives for seismic exploration in oil and gas industries, where it helps in creating shock waves to map underground geological formations. Its use is strictly regulated due to its hazardous nature and potential for misuse.
