4-amino-2,6-dimethylbenzonitrile; CAS No.: 114820-10-9; 4-amino-2,6-dimethylbenzonitrile. PROPERTIES: 4-amino-2,6-dimethylbenzonitrile appears as a white to off-white crystalline powder with a molecular weight of 161.2 g/mol. It demonstrates a melting point in the range of 72-75 C and limited water solubility, though it dissolves readily in organic solvents such as methanol, ethanol, and dichloromethane. The compound exhibits moderate stability under ambient conditions but should be stored in a cool, dry place (below 30 C) in a tightly sealed container to prevent degradation. Exposure to excessive heat or direct sunlight should be avoided. From a safety perspective, standard laboratory precautions are recommended, including the use of personal protective equipment. The amine functionality may render it moderately toxic if ingested, and appropriate first aid measures should be followed in case of exposure. APPLICATIONS: 4-amino-2,6-dimethylbenzonitrile is prominently utilized in the pharmaceutical industry as a versatile intermediate for the synthesis of various medicinal agents. Its structural framework, featuring the amino and nitrile groups in specific positions, makes it suitable for the preparation of antipsychotic drugs and antidepressants, as documented in medicinal chemistry journals. In materials science, the compound serves as a building block for certain types of conductive polymers, where the electron-donating methyl groups enhance conjugation properties. Additionally, it functions as a starting material for the production of specialty dyes and pigments, particularly those requiring thermal stability. Through chemical modification of the amino group, it can be converted into various heterocyclic systems, expanding its application scope in organic synthesis, as described in recent advances in heterocyclic chemistry.
