About Malononitrile, ≥99%

Malononitrile is a nitrile building block carrying the CAS registry number 109-77-3 with a typical assay of ≥99%. With the molecular formula C3H2N2, it has a molar mass of 66.06 g/mol. Systematically, it is named propanedinitrile. It is also known as Dicyanomethane or Malonic dinitrile.

The material typically appears as colourless to white powder or crystals or chunks. Literature values give a melting point of 30-32 °C. Store it at 2–8 °C, in a tightly closed container. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for organic synthesis and API synthesis. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Malononitrile in 100 g, 500 g and 5 kg packs with a batch-specific COA, and ship to customers worldwide.
