Overview
2,3,5,6-Tetrafluorobenzoic acid acyl chloride (CAS: 1003-74-3) is a high-purity fluorinated intermediate synthesized via chlorination of the parent acid using thionyl chloride. Molecular formula: C7H2ClF4O.
Application
- Pharmaceutical synthesis for fluoro-substituted active ingredients.
- Agrochemical production of herbicides and fungicides.
- Material science for advanced polymer precursors.
Precautions
Store under inert atmosphere at 2-8°C. Strictly avoid moisture to prevent hydrolysis. Use full PPE due to severe corrosivity and lachrymatory effects.
