Dibromoneopentyl glycol (3296-90- is generally harmless to water. Do not drain the material into the surrounding environment unless permitted by the government. Store in a dry, ventilated and sealed place at room temperature and away from light.Discount Dibromoneopentyl Glycol website:http://www.rixingxincai.com/br....ominated-flame-****a
