Description

2,4-Dichloro-5-methylbenzotrifluoride (CAS No. 115571-61-4) is a high-purity halogenated aromatic compound with the molecular formula C₈H₅Cl₂F₃. This specialty chemical is characterized by its trifluoromethyl and chloro substituents on a methylated benzene ring, offering unique reactivity and stability for advanced synthetic applications. Its IUPAC name, 1,5-dichloro-2-methyl-4-(trifluoromethyl)benzene, reflects its precise structural configuration. This compound is supplied as a clear to pale-yellow liquid (or low-melting solid, depending on storage conditions) with exceptional purity (>98% by GC analysis), making it ideal for pharmaceutical intermediates, agrochemical synthesis, and material science research. Proper handling under inert atmosphere is recommended due to its moisture-sensitive nature. Packaged in amber glass bottles or sealed drums under nitrogen to ensure prolonged shelf stability.

Application

2,4-Dichloro-5-methylbenzotrifluoride serves as a versatile building block in organic synthesis, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) and crop protection agents. Its electron-deficient aromatic ring system enables efficient nucleophilic substitution reactions for creating complex heterocycles. Researchers utilize this compound in Suzuki-Miyaura coupling reactions to construct biaryl scaffolds with enhanced lipophilicity. In material science, it acts as a precursor for liquid crystal monomers and flame-retardant additives.
