Properties:
Diethyl ethoxymethylenemalonate (EMME) is a colorless liquid with a molecular weight of 216.23. It is an important intermediate in organic synthesis, particularly in the production of quinolone antibiotics. It is soluble in common organic solvents but insoluble in water.
Application:
EMME is widely used in pharmaceutical and chemical synthesis, especially as a key intermediate in the preparation of fluoroquinolone antibiotics (e.g., ciprofloxacin, norfloxacin). It also serves as a building block in the synthesis of heterocyclic compounds, agrochemicals, and fine chemicals.
Package and Storage:
25-200 kg/drum. Store in a cool, dry place (2-8°C recommended) away from moisture and light. Keep the container tightly sealed to prevent degradation.
