Dimethyl 1,2-cyclopropanedicarboxylate(CAS: 702-28-3)

Dimethyl 1,2-cyclopropanedicarboxylate is a colorless crystalline solid with a molecular weight of approximately 148.15 g/mol. It has a melting point around 53-54°C and is slightly soluble in water. It is reactive towards bases and can undergo ester hydrolysis. The compound is stable under normal storage conditions but should be kept away from heat and strong acids.

Dimethyl 1,2-cyclopropanedicarboxylate can be synthesized via the esterification of 1,2-cyclopropanedicarboxylic acid with dimethyl carbonate. Common catalysts include sulfuric acid or toluene sulfonic acid. The reaction is typically carried out under reflux conditions, and the yield can be improved by using appropriate solvents and maintaining optimal reaction conditions.

Dimethyl 1,2-cyclopropanedicarboxylate is used in various industries. It serves as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antibiotics and antiviral agents. It is also used in the manufacturing of polymers, as a monomer for producing specific types of plastic. Additionally, the compound has applications in the development of sensors and semiconductors due to its unique chemical properties.

When handling Dimethyl 1,2-cyclopropanedicarboxylate, it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats. The substance should be stored in a cool, dry place away from heat and strong acids. In case of a spill, it should be cleaned up immediately using appropriate absorbent materials. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
