Introduction
3-Fluoro-4-nitrobenzoic acid (3-F4NBA) is a crystalline compound with the molecular formula C₇H₄FNO₄ and a molecular weight of 185.11 g/mol. It is widely recognized as a key intermediate in pharmaceutical synthesis, particularly for producing 3-fluoro-4-nitrobenzaldehyde, a critical module in drug development. The compound is also utilized in agrochemicals and organic synthesis, offering a versatile platform for introducing fluorine and nitro functional groups into molecules. 3-F4NBA is typically synthesized from 3-fluoro-4-nitro-toluene or via nitration of 3-fluorobenzoic acid. It exhibits moderate thermal stability, decomposing above 372.8°C, and is soluble in organic solvents like methanol and DMSO. Due to its reactivity and applications, 3-F4NBA is a valuable reagent in both research and industrial chemistry.
Usage： Pharmaceutical Intermediates.
Packaging and Shipping： 25KG/drum or as per buyer’s requirements.
Storage: Storage in ventilated low temperature dry warehouse; Keep container closed and separately from open flame and heat source.
