Key Properties and Physical CharacteristicsMalononitrile features a neutral to slightly acidic pH, a melting point of 31-33C, and a boiling point of 220C (with decomposition). Its density is 1.12 g/cm and it is highly soluble in water, ethanol, and ether. The compound has a refractive rate of n20/D 1.441 and emits a faint, nitrile odor. These properties make it versatile for various industrial and laboratory applications.
Storage and Stability GuidelinesFor optimal stability, malononitrile should be tightly sealed and stored in a cool, dry environment, away from moisture and strong oxidizers. Proper storage not only preserves its purity but also ensures a shelf life of up to two years. Its packaging options include HDPE drum, fiber drum, or bag packing, tailored to industrial requirements.
Safety Precautions and HandlingMalononitrile is toxic if swallowed, inhaled, or in contact with skin, and carries the signal word Danger. It is regulated as a hazardous chemical, with UN Number 2811 and EC Index Number 608-005-00-4. Use protective equipment and handle only in well-ventilated areas to minimize exposure. Emergency procedures and compatibility assessments are essential during handling.
Applications in Industry and ResearchWidely utilized as an intermediate in organic synthesis, malononitrile plays a vital role in manufacturing pharmaceuticals, agrochemicals, amino acids, and dyestuffs. Its highly polar nature and reactivity make it suitable for diverse chemical processes, benefiting research labs and industrial manufacturing alike.
