Dimethyl methylmalonate(CAS: 609-02-9)

Dimethyl methylmalonate (CAS: 609-02-9) is a colorless, crystalline solid with a molecular weight of approximately 122.11 g/mol. It is slightly soluble in water but miscible with organic solvents like ethanol and acetone. Chemically, it is moderately reactive, particularly in the presence of acids and bases, and can undergo esterification and other organic reactions.

Dimethyl methylmalonate is typically synthesized via the condensation of propionyl chloride with ethyl malonate. Common catalysts include phosphoric acid or sulfuric acid, providing a yield of up to 80%. The reaction is selective and efficient, making it a standard method in organic synthesis.

Dimethyl methylmalonate is widely used in the pharmaceutical industry for the synthesis of various drugs, particularly as a precursor for amino acids and other intermediates. It is also utilized in the polymer industry as a plasticizer and in the sensor industry for its role in developing specific chemical sensors. Additionally, it has applications in semiconductor manufacturing as a cleaning agent.

When handling Dimethyl methylmalonate, it is essential to wear protective equipment such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight and heat sources. In case of a spill, it should be handled with caution using absorbent materials, and proper personal protective equipment should be worn. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
