4-fluorocinnamic Acid, CAS No. : afaf, EINECS No. : ffafsafa

As food additive.Applications in liquid crystal materials:The liquid crystal material for display must satisfy the most basic requirements such as wide operating temperature range, low operating voltage and quick response. Fluorine atom has some special properties such as module effect, electron effect, barrier effect and osmosis effect. Therefore, the introduce of fluorine atom in the liquid crystal material will improve many properties of the liquid crystal.
