4-Bromo-2-fluoroacetanilide, a compound identified by its CAS number 326-66-9, has carved a significant niche in the realm of advanced chemical synthesis. Its unique structural features—specifically the presence of both a bromine atom and a fluorine atom on the acetanilide backbone—make it a highly versatile building block for creating complex organic molecules.

In the pharmaceutical industry, this intermediate plays a crucial role in the synthesis of various Active Pharmaceutical Ingredients (APIs). Researchers and formulators often purchase it as a starting material to construct novel drug candidates. The bromine atom serves as an excellent leaving group or a point for cross-coupling reactions (like Suzuki or Buchwald-Hartwig couplings), while the fluorine atom can modulate pharmacokinetic properties such as metabolic stability and lipophilicity. This dual functionality allows for precise molecular engineering, which is essential in modern drug discovery.

Beyond pharmaceuticals, 4-Bromo-2-fluoroacetanilide finds applications in the agrochemical sector. It can be a precursor to specialized herbicides, insecticides, or fungicides, where its structural elements contribute to the efficacy and selectivity of the final product. The demand for innovative crop protection solutions drives the need for reliable suppliers of such key intermediates.

For chemists engaged in custom synthesis or contract research, having access to high-purity 4-Bromo-2-fluoroacetanilide is indispensable. Many suppliers, particularly manufacturers from China, offer this compound with purity levels typically above 98% or 99%. This ensures that reactions proceed with minimal side products, leading to higher yields and purer final products. When you are looking to buy this chemical, consider engaging with suppliers that can provide batch-to-batch consistency and comprehensive technical documentation.

The availability and competitive price of 4-Bromo-2-fluoroacetanilide from global suppliers, especially from China, make it an accessible component for both academic research and industrial-scale production. Whether you are developing new therapeutic agents or advanced agricultural chemicals, understanding the synthetic utility of this compound is key to unlocking new possibilities in chemical innovation.
