Dimethyl isopropylmalonate(CAS: 51122-91-9)

Dimethyl isopropylmalonate is a colorless to light yellow liquid with a molecular weight of approximately 184.24 g/mol. It is slightly soluble in water but miscible with many organic solvents. Chemically, it is characterized by its reactivity towards nucleophiles and its ability to undergo esterification and amidation reactions. Its crystalline form is not common, but it can be obtained under specific conditions.

Dimethyl isopropylmalonate can be synthesized through the reaction of isopropylmalononitrile with methyl iodide in the presence of a base like potassium carbonate. The method involves protecting the carboxylic acid group and then converting it to the corresponding ester. The reaction yields a high purity product with good selectivity and high yield.

Dimethyl isopropylmalonate is widely used in the pharmaceutical industry for the synthesis of certain drugs and intermediates. It is also utilized in the polymer industry for the modification of polymers and in the semiconductor industry for photoresist applications. Additionally, it has applications in the production of sensors and as a reagent in analytical chemistry.

When handling Dimethyl isopropylmalonate, it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats. Always work in a well-ventilated area or a fume hood to avoid inhalation. Store the compound at room temperature in a sealed, dry container to prevent degradation. In case of spills, contain them and dispose of according to local regulations. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures and storage guidelines.
