Methoxy Propanol (PM)

Methoxy propanol (also known as propylene glycol monomethyl ether, 1-methoxy-2-propanol, PM, and PGME), is a colourless liquid that is soluble in water and is highly flammable.  It is a methoxy alcohol derivative and has a formula of C4H10O2.

Methoxy Propanol (PM)


Methoxy propanol is produced by the reaction of 1,2-epoxy propane and methanol in the presence of a catalyst, and this is then followed by distillation.

The worldwide annual production of methoxy propanol is approximately 100,000 to 500,000 tonnes.

Storage and Distribution

Methoxy propanol has a specific gravity of 0.924 and a flash point of 33° C and is therefore highly flammable so should be stored in a cool, dry and well-ventilated area that is free from sources of ignition.  For transport purposes, methoxy propanol is classified as packing group III and hazard class 3 and is an irritant.


Methoxy propanol is predominately used in the manufacture of propylene glycol methyl ether acetate (otherwise known as PMA) and is also used in industrial and commercial products including paints, varnishes, inks, synthetic resin and rubber adhesives, and automotive and oven cleaners.  It is also used as a cleaning agent in the LCD and electronics industry.
