 Propylene glycol methyl ether (CAS NO.1320-67-8) is mainly used for excellent solvent of nitro-fiber, alkyd resins and maleic anhydride modified phenolic resin, and also can be used as additive of brake fluid and  jet fuel antifreeze.

Glycol ethers are on the Community Right-To-Know List.

An eye irritant. Many glycol ether compounds have dangerous human reproductive effects. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO₂, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHYLENE GLYCOL METHYL ETHER and GLYCOL ETHERS.

 Propylene glycol methyl ether ,its cas register number is 1320-67-8. It also can be called Methoxy-1-propanol ; Propanol, 1(or 2)-methoxy- ; 1-propanol, 1-methoxy- and 1-methoxypropan-1-ol .It is a methoxy-alcohol derivative. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water.
