Methyl (3-amino-2,6-difluorophenyl)acetate(CAS: 361336-80-3)

Methyl (3-amino-2,6-difluorophenyl)acetate is a crystalline compound with a molecular weight of approximately 223.08 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. The compound exhibits moderate reactivity, particularly towards nucleophiles due to the presence of the amino and fluoro substituents. It is stable under normal laboratory conditions but should be stored in a cool, dark place to prevent photo-degradation.

Methyl (3-amino-2,6-difluorophenyl)acetate is synthesized via a multi-step process involving the reduction of a precursor diazonium salt followed by the coupling reaction with a methyl ester. Commonly used catalysts include palladium-based complexes. The reaction typically yields a high selectivity towards the desired product with a yield of around 75-85%. Care must be taken to use appropriate safety equipment and handle the intermediate diazonium salt under inert conditions to prevent unwanted reactions.

Methyl (3-amino-2,6-difluorophenyl)acetate finds applications in the pharmaceutical industry for the synthesis of active pharmaceutical ingredients (APIs). It is also used in the polymer industry as a monomer for the production of speciality polymers. Additionally, it is utilized in the development of sensors and semiconductors due to its unique electronic properties.

When handling Methyl (3-amino-2,6-difluorophenyl)acetate, it is crucial to wear proper personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. The compound should be handled in a well-ventilated area, preferably under a fume hood, to minimize exposure. Spills should be immediately cleaned up using appropriate absorbent materials, and the area should be ventilated thoroughly. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures and disposal instructions.
