5,7-Dimethoxy-3-methyl-1H-indazole(CAS: 154876-15-0)

5,7-Dimethoxy-3-methyl-1H-indazole (CAS: 154876-15-0) is a crystalline solid with a molecular weight of approximately 212.2 g/mol. It has a low water solubility and is moderately soluble in common organic solvents like methanol and dichloromethane. Reactivity-wise, it is stable under normal conditions but can undergo substitution reactions in the presence of strong bases or acids. It is characterized by its unique UV-Vis absorption spectrum and is often used in organic synthesis and as a precursor in various chemical processes.

5,7-Dimethoxy-3-methyl-1H-indazole (CAS: 154876-15-0) can be synthesized via a multistep route involving the protection of an amine, subsequent indole formation, and deprotection. Commonly, amines are protected to form a tertiary amine, followed by base-promoted indole formation. The product is then deprotected under acidic conditions. This method provides good yields and high selectivity, making it a suitable approach for industrial synthesis.

5,7-Dimethoxy-3-methyl-1H-indazole (CAS: 154876-15-0) finds applications in pharmaceuticals, where it serves as a precursor in the synthesis of drugs. It is also used in polymer chemistry for the development of functional materials, in sensor technology for its photoresponsive properties, and in semiconductor manufacturing for its use in organic electronic devices.
