2,4-Dicyanoaniline(CAS: 19619-22-8)

2,4-Dicyanoaniline (CAS: 19619-22-8) is a crystalline solid with a molecular weight of approximately 174.1 g/mol. It has a high melting point of around 152-153°C. The compound is poorly soluble in water but soluble in common organic solvents such as ethanol and dichloromethane. It exhibits moderate reactivity, particularly in electrophilic aromatic substitution reactions.

2,4-Dicyanoaniline (CAS: 19619-22-8) is usually synthesized via the condensation of dicyanodiamine with an appropriate anilide, such as p-anisic anilide, in the presence of a strong acid catalyst like sulfuric acid. The reaction is typically carried out in aprotic solvents under reflux conditions. The yield can be up to 85%, and the product is isolated by recrystallization.

2,4-Dicyanoaniline (CAS: 19619-22-8) is primarily used in the pharmaceutical and polymer industries. It serves as a precursor for pharmaceutical intermediates and is also used in the synthesis of dyes and pigments. Additionally, it has applications in the production of organic semiconductors and gas sensors.

When handling 2,4-Dicyanoaniline (CAS: 19619-22-8), it is essential to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. This compound is highly toxic and corrosive, so work should be conducted in a fume hood. Spills should be cleaned up immediately using appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed safety information.
