5-Bromo-2-methyl-1H-indole(CAS: 1075-34-9)

5-Bromo-2-methyl-1H-indole is a crystalline solid with a molecular weight of approximately 219.03 g/mol. It has low water solubility and is slightly soluble in common organic solvents like ethanol and acetone. The compound is moderately reactive, especially towards nucleophiles, and can undergo substitution reactions. It is stable under normal storage conditions but should be protected from light.

5-Bromo-2-methyl-1H-indole is commonly synthesized via alkylation of indole followed by bromination. The alkylation step often uses methyl iodide as the alkylating agent in the presence of a base like sodium hydride. Bromination is typically carried out using bromine in the presence of a Lewis acid catalyst, such as aluminum bromide, to ensure high yield and selectivity.

5-Bromo-2-methyl-1H-indole is used in various industries, particularly in the pharmaceutical sector for the synthesis of drug candidates. It is also utilized in the polymer industry for developing functional polymers and in the sensor industry for the fabrication of gas sensors. Additionally, it has potential applications in the semiconductor industry for creating specific materials.

When handling 5-Bromo-2-methyl-1H-indole, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated fume hood to minimize exposure. Spills should be cleaned up using appropriate materials and proper disposal methods as outlined in the safety data sheet (SDS). The compound should be stored in a cool, dry place away from sources of heat and light.
