Description

4-Fluoro-3-(trifluoromethyl)benzaldehyde (CAS No. 67515-60-0) is a high-purity fluorinated aromatic aldehyde with the molecular formula C₈H₄F₄O. This compound features a benzaldehyde core substituted with a fluorine atom at the 4-position and a trifluoromethyl group at the 3-position, making it a versatile building block for synthetic organic chemistry and pharmaceutical research. Its unique electronic properties, imparted by the electron-withdrawing trifluoromethyl and fluorine groups, enhance reactivity in nucleophilic aromatic substitution and cross-coupling reactions. Ideal for use in the synthesis of fluorinated liquid crystals, agrochemicals, and bioactive molecules, this reagent is rigorously tested for purity (typically ≥97% by GC or HPLC) and is supplied in sealed packaging under inert conditions to ensure stability. Available in quantities from grams to kilograms, it is a critical intermediate for researchers developing advanced materials and fine chemicals.

Application

4-Fluoro-3-(trifluoromethyl)benzaldehyde is widely used as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals due to its reactive aldehyde group and electron-deficient aromatic ring. It serves as a precursor for liquid crystal materials in display technologies, where its fluorine content improves thermal and chemical stability. Researchers also employ it in metal-catalyzed cross-coupling reactions to construct complex fluorinated scaffolds for drug discovery programs targeting CNS and inflammatory diseases.
