Hexamethylphosphoramide (HMPA) is a high-polarity organic solvent and reagent widely used in organic synthesis. Its molecular formula is (CH3)2N3P=O and CAS number is 68-12-2. Produced via the reaction of dimethylamine with phosphorus oxychloride followed by hydrolysis, it serves as a critical non-protic solvent.
HMPA is classified as a potential carcinogen requiring strict handling protocols. Storage must be in cool, well-ventilated areas away from oxidizers. Personnel must wear appropriate PPE including respirators and chemical-resistant gloves to prevent inhalation or skin contact.
