2,3-Dimethyl-1H-indole(CAS: 91-55-4)

2,3-Dimethyl-1H-indole (CAS: 91-55-4) is a crystalline solid with a molecular weight of approximately 129.18 g/mol. It is sparingly soluble in water but soluble in organic solvents like ethanol, acetone, and dichloromethane. Chemically, it is moderately reactive towards electrophiles and nucleophiles. It is stable under normal conditions but may undergo thermal degradation at high temperatures.

2,3-Dimethyl-1H-indole (CAS: 91-55-4) is commonly synthesized via the indole synthesis route, starting from aniline and methyl acetoacetate. The reaction typically uses a catalyst like palladium acetate and a base like triethylamine. High yields can be achieved with good regioselectivity.

2,3-Dimethyl-1H-indole (CAS: 91-55-4) is used in various industries. It is a key intermediate in the synthesis of pharmaceuticals, including antipsychotics and antidepressants. It is also used in the production of fragrances and as a precursor in the development of polymers and sensors. Its electronic properties make it suitable for semiconductor applications.

When handling 2,3-Dimethyl-1H-indole (CAS: 91-55-4), it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be handled with care, and the Safety Data Sheet (SDS) should be consulted for specific spill response procedures. Storage should be in a cool, dry place away from direct sunlight.
