For chemists, researchers, and procurement managers involved in chemical synthesis and formulation, understanding the fundamental properties of key solvents is crucial. 1,3-Dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone, identified by CAS number 7226-23-5 and commonly abbreviated as DMPU, is a polar aprotic solvent that warrants detailed examination.

DMPU is a cyclic urea derivative, possessing a molecular formula of C6H12N2O and a molecular weight of approximately 128.18 g/mol. Its physical appearance is typically a colorless to slightly yellow, clear liquid. This chemical characteristic is vital for applications where visual clarity is important. Key physical properties include a boiling point of around 246.5 °C, indicating its suitability for reactions requiring elevated temperatures, and a melting point of -14 °C, meaning it remains liquid under standard laboratory conditions. Its density is approximately 1.06 g/mL at 25 °C.

Chemically, DMPU functions as a highly effective polar aprotic solvent. This classification means it has a significant dipole moment and high dielectric constant, allowing it to solvate cations efficiently and stabilize polar transition states in chemical reactions. This property is fundamental to its utility in organic synthesis, enabling reactions that might otherwise be slow or unfeasible. As a manufacturer, we ensure that our DMPU consistently exhibits these critical properties, typically with a purity exceeding 99.0%.

One of the most significant advantages of DMPU is its role as a safer substitute for Hexamethylphosphoramide (HMPA). While HMPA offers similar solvency characteristics, its known carcinogenicity makes DMPU a preferred choice for chemical manufacturers and researchers prioritizing health and safety. This substitution is not merely a matter of compliance but a proactive step towards more responsible chemical handling and production. When you choose to buy DMPU, you are opting for a solvent that balances performance with reduced hazard.

DMPU's applications span across various industries, including pharmaceutical intermediates, agrochemicals, and electronics. Its miscibility with water and many organic solvents further enhances its versatility.
