O le vailaʻau vailaʻau mo Neopentyl glycol (NPG) o le C5H12O2, ma o se propane-1,3-diol o loʻo tauaveina vaega methyl e lua i le tulaga 2. Neopentyl glycol e soluble i le vai, benzene, chloroform, ma sili ona soluble i le ethanol ma le diethyl eter. . O le Neopentylglycol (NPG) o se polyalcohol tulaga ese e ofoina atu faʻamanuiaga sili atu i le tele o faʻaoga faʻaoga ona o le maualuga o vailaʻau ma le mafanafana. O se diol tulaga ese o loʻo ofoina atu faʻamanuiaga maualuga i le tele o faʻaoga faʻaoga. O nei tulaga lelei e maua mai i lona fausaga fa'a-kemikolo. O le nofoaga o vaega hydroxyl i luga ole carbon atoms muamua e mafai ai ona esterification vave. E le gata i lea, o vaega methyl e lua, nai lo le masani e lua hydrogen atoms, i luga o le alpha carbon atom e nafa ma le maualuga o vailaʻau ma le mautu o le Neopentylglycol ma ona mea e maua mai ai.
