'''Trimethylolethane trinitrate''' ('''TMETN'''), also known as '''metriol trinitrate''' ('''METN''', '''MTN''', '''METRTN''') or '''nitropentaglycerin''', is a nitro ]. It is a ] similar to ]. It is a transparent oily liquid, colorless to light brown. It is odorless. It is used in some ]s and ]s as a ]. Its chemical formula is CH<sub>3</sub>-C(CH<sub>2</sub>-O-NO<sub>2</sub>)<sub>3</sub>. '''Trimethylolethane trinitrate''' ('''TMETN'''), also known as '''metriol trinitrate''' ('''METN''', '''MTN''', '''METRTN''') or '''nitropentaglycerin''', is a ]. It is a ] similar to ].

TMETN was first prepared and patented in Italy under name '''Metriolo'''. Germans began producing it before WWII when it was demonstrated to be an erosion and flash reducing agent in smokeless powders. It is a liquid explosive with properties similar to nitroglycerin but more stable to heat. It is prepared by ] of ] (metriol). It does not induce headaches. TMETN was first prepared and patented in Italy under name '''Metriolo'''. Germans began producing it before World War II, when it was demonstrated to be an erosion and flash-reducing agent in smokeless powders.

TMETN can be initiated by friction, impact, and electrostatic discharge. It can be used as a high viscosity plasticizer-binder together with ], but its poor coloiding properties made such use rare; long-term milling can however assist here; success can also be achieved by adding an inert plasticizer and a volatile solvent/colloiding agent.
