Methyl Ethyl Ketone, HPLC Grade
Methyl Ethyl Ketone (MEK), also known as Butanone, is a highly versatile organic compound that exceeds A.C.S. specifications and is specifically formulated for use in high-performance liquid chromatography (HPLC). This colorless liquid is characterized by its sweet, sharp odor, reminiscent of acetone, and is soluble in water, making it an invaluable asset in laboratory environments.
Key Features
- High Purity: Designed for HPLC applications, ensuring accurate and repeatable results.
- Rigorous Processing: Methyl Ethyl Ketone is glass distilled and submicron filtered, providing exceptional purity and clarity.
- Chemical Stability: Unlike acetone, MEK has a higher boiling point and a slower evaporation rate, allowing for more controlled reactions.
- Applications: Commonly used as an industrial solvent, MEK is effective in dissolving polystyrene and is utilized as a welding agent in model cement.
