Welcome to buy Hexamethylphosphoramide CAS 680-31-9 from us. Hexamethylphosphoric triamide, also known as hexaphosphoramide and hexamethylphosphoramide, is prepared by the reaction of dimethylamine and phosphorus oxychloride. Molecular weight 179.2. It is colorless or light yellow transparent liquid. Slightly fishy and astringent. Soluble in polar and non-polar solvents. It is miscible with common plasticizers such as dioctyl phthalate, dioctyl sebacate, and triphenyl phosphite in any proportion. Toxicity is similar to that of phosphate esters. Avoid contact with skin. The container should be tightly closed to prevent leakage and deterioration due to water absorption.
