What is Dimethyl Malonate?

Dimethyl Malonate (DMM) is an organic compound widely used as a chemical intermediate in agrochemicals, and dyes. It is a clear, colorless, flammable liquid with a fruity odor and is known for its excellent reactivity due to the active methylene group. DMM is commonly used in Knoevenagel condensations and malonic ester syntheses.

In agrochemicals, it is used in the synthesis of herbicides and plant growth regulators.
