In the vast landscape of organic chemistry, specific molecules emerge as indispensable tools for innovation and production. 5-Nitroindazole, identified by its CAS number 5401-94-5, is one such compound that plays a crucial role as a versatile building block in chemical synthesis and advanced research and development (R&D). Its unique structural features and reactivity make it a sought-after intermediate for chemists worldwide.

5-Nitroindazole is characterized by its indazole core, a bicyclic aromatic system, coupled with a nitro group (-NO2) at the 5-position. This functionalization imparts specific electronic and steric properties that are highly advantageous in organic transformations. Typically presenting as a light yellow crystalline solid, it possesses a melting point of approximately 207°C. Its molecular formula is C7H5N3O2, with a molecular weight of about 163.13 g/mol. The compound's structure allows for various derivatization pathways, making it a flexible starting material for synthesizing more complex organic molecules.

The utility of 5-Nitroindazole spans multiple domains within chemical synthesis. It is particularly recognized as a key intermediate in the pharmaceutical industry. For instance, it serves as a precursor in the synthesis of Fluoxetine HCl, a widely prescribed antidepressant. This application highlights its direct contribution to human health and well-being. Researchers and manufacturers seeking to procure this compound often look for reliable 5-Nitroindazole manufacturers in China, known for their large-scale production capacities and competitive pricing. Obtaining a quote for 5-Nitroindazole is a common first step for businesses integrating it into their supply chain.

Beyond pharmaceutical applications, 5-Nitroindazole is a valuable reagent in general organic synthesis. Its nitro group can be reduced to an amine, opening pathways to amide formations or other nitrogen-containing functionalizations. The indazole ring itself can undergo various electrophilic or nucleophilic substitution reactions depending on the conditions. This inherent versatility makes it an attractive molecule for exploring new chemical reactions and developing novel compounds for diverse industrial applications, from specialty chemicals to advanced materials.

For researchers and chemical procurement managers, sourcing high-purity 5-Nitroindazole is essential for reproducible results and efficient synthesis. Companies that specialize in fine chemicals and pharmaceutical intermediates, such as NINGBO INNO PHARMCHEM CO.,LTD., offer this compound with guaranteed assay values, often exceeding 98% or 99% purity. By partnering with a trusted 5-Nitroindazole supplier, laboratories and manufacturing facilities can ensure a consistent and high-quality supply, facilitating their ongoing R&D efforts and production requirements.
