Cas no 206362-87-0 (Methyl 4-chloro-3-fluorobenzoate)

Methyl 4-chloro-3-fluorobenzoate (CAS: 403-17-8) is a fluorinated and chlorinated aromatic ester with the molecular formula C8H6ClFO2. This compound serves as a versatile intermediate in organic synthesis, particularly in pharmaceutical and agrochemical applications. Its distinct structural features, including the electron-withdrawing chloro and fluoro substituents on the benzoate ring, enhance its reactivity in cross-coupling reactions, nucleophilic substitutions, and other transformations. The ester group further facilitates derivatization into acids, amides, or other functionalized products. With high purity (>98%) and stability under standard conditions, it is suitable for precision synthesis. Its well-defined spectroscopic properties (e.g., NMR, IR) aid in reaction monitoring and quality control. The compound’s balanced lipophilicity also makes it valuable in drug design for optimizing bioavailability.
