Imiti ya chimique ya Neopentyl glycol (NPG) ni C5H12O2, kandi ni propane-1,3-diol itwara amatsinda abiri ya methyl kumwanya wa 2.Neopentyl glycol irashonga mumazi, benzene, chloroform, kandi igashonga cyane muri Ethanol na diethyl ether . Neopentylglycol (NPG) ninzoga idasanzwe itanga inzoga nziza murwego rwo gukoresha amaherezo kubera imiti myinshi nubushyuhe bukabije. Ni diol idasanzwe itanga ibyiza byo gukora murwego rwohejuru-gukoresha porogaramu. Izi nyungu zikomoka kumiterere yimiti. Ikibanza cyamatsinda ya hydroxyl kuri atome yambere ya karubone ituma esterification yihuta. Byongeye kandi, amatsinda abiri ya methyl, aho kuba atome ebyiri zisanzwe za hydrogène, kuri atome ya karubone ya alfa ishinzwe umutekano mwinshi wa Neopentylglycol n'ibiyikomokaho.
