4-Amino-2-fluoro-3-methylbenzonitrile(CAS: 757247-93-1)

4-Amino-2-fluoro-3-methylbenzonitrile is a white crystalline solid with a molecular weight of approximately 202.14 g/mol. It has a low solubility in water but is more soluble in organic solvents. The compound is moderately reactive, showing basic properties due to the amino group and can undergo nucleophilic substitution reactions. It is stable under normal conditions but should be stored in a cool, dry place away from direct sunlight and heat sources. It is not flammable but may pose a skin and eye irritant risk if not handled properly.

4-Amino-2-fluoro-3-methylbenzonitrile is typically synthesized through a multi-step process involving the fluoroamination of 3-methylbenzonitrile with an appropriate amine under mild conditions. The synthesis often employs a catalytic system using palladium-based catalysts, and the product is usually obtained with good selectivity and yield. The specific reaction conditions, such as temperature, pressure, and solvent choice, can vary depending on the synthesis method used.

4-Amino-2-fluoro-3-methylbenzonitrile finds applications in the pharmaceutical industry, where it is used as an intermediate in the synthesis of various drug candidates. It also has potential uses in the polymer industry for developing novel materials with specific properties. Additionally, it is used in the preparation of sensors and semiconductors, contributing to the development of advanced materials and technologies.

When handling 4-Amino-2-fluoro-3-methylbenzonitrile, it is essential to wear appropriate personal protective equipment (PPE) including gloves, goggles, and lab coat. It should be handled in a well-ventilated area or under a fume hood to minimize inhalation risk. Spills should be cleaned up carefully using appropriate disposal methods, and the area should be thoroughly washed. Always refer to the Safety Data Sheet (SDS) for detailed information on handling and emergency procedures.
