1-(4-Chloro-3-fluorophenyl)methanamine(CAS: 72235-58-6)

1-(4-Chloro-3-fluorophenyl)methanamine is a white crystalline solid with a molecular weight of approximately 225.58 g/mol. It has a low solubility in water but is more soluble in organic solvents such as ethanol and acetone. The compound shows moderate reactivity and can undergo nucleophilic substitution reactions. It is stable under normal storage conditions but should be protected from moisture and light.

1-(4-Chloro-3-fluorophenyl)methanamine is typically synthesized via a multi-step process involving the protection of an amine, formation of an intermediate, and subsequent deprotection. Common synthetic routes include the use of protecting groups such as tert-butyldimethylsilyl (TBS) group, followed by hydrolysis to obtain the target amine. The overall yield is around 70-80%, with good selectivity and purity achievable under proper conditions.

1-(4-Chloro-3-fluorophenyl)methanamine is primarily used in pharmaceuticals, where it serves as an intermediate for the synthesis of various drugs. It is also utilized in the polymer industry for the development of advanced materials, and in the sensor industry for the production of gas sensors. Additionally, it finds applications in the semiconductor industry as a dopant precursor.

When handling 1-(4-Chloro-3-fluorophenyl)methanamine, it is crucial to use appropriate personal protective equipment (PPE), including gloves and safety goggles. The compound should be handled in a well-ventilated area or a fume hood to minimize exposure to vapor. In case of a spill, it should be immediately cleaned up using appropriate absorbent materials, and the area should be flushed with water.
