4,6-Difluoro-2-methyl-1H-benzimidazole(CAS: 874814-18-3)

4,6-Difluoro-2-methyl-1H-benzimidazole is a white to off-white crystalline solid with a molecular weight of approximately 170.07 g/mol. It is slightly soluble in water and more soluble in common organic solvents like DMSO and DMF. Chemically, it exhibits good stability under normal conditions but can react with strong acids or bases to form derivatives. It is used in various applications due to its unique chemical properties.

4,6-Difluoro-2-methyl-1H-benzimidazole can be synthesized via the condensation of 2-methylbenzaldehyde with 1,3-difluorobenzene in the presence of a Lewis acid catalyst, such as aluminum chloride, at a temperature of around 100°C. The reaction proceeds with high selectivity and yield, producing the desired product with minimal by-products.

4,6-Difluoro-2-methyl-1H-benzimidazole is used in the pharmaceutical industry as an intermediate for the synthesis of drugs with antiproliferative and anticancer effects. It also finds applications in the polymer industry, where it serves as a potential monomer or additive. Additionally, it is utilized in the development of sensor technology and in the field of semiconductors.

When handling 4,6-Difluoro-2-methyl-1H-benzimidazole, it is essential to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a laboratory coat. Ensure work is conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling and disposal information.
