Overview
Malononitrile is a highly reactive organic compound containing two nitrile groups. It is a key building block in organic synthesis due to its active methylene group, which readily participates in condensation and cyclization reactions. Its versatility makes it valuable across multiple industries.

Applications

• Pharmaceuticals: Used in the synthesis of important drugs such as vitamin B1 (thiamine), methotrexate (an anticancer and immunosuppressive agent), and other pharmaceutical intermediates.

• Agrochemicals: Precursor for the production of pesticides, herbicides, and fungicides.

• Dyes and pigments: Employed in the manufacture of specialty dyes and colorants.

• Gold extraction: Acts as a complexing agent in gold recovery processes, particularly in cyanide-free or alternative leaching systems.

• Organic synthesis: Building block for heterocyclic compounds, pharmaceuticals, and fine chemicals.

Handling and Storage

• Store in a cool, dry, well-ventilated area, away from strong oxidizers and acids.

• Keep containers tightly sealed to prevent moisture absorption and contamination.

• Handle with appropriate personal protective equipment (gloves, safety goggles, lab coat).

• Avoid inhalation of dust and contact with skin and eyes.

Packaging
Standard packaging: 50 kg net in iron drums. Custom packaging available upon request.

Quality Assurance
