Applications

Eaton's Reagent is used in the synthesis fluorine-based hole-transporting material, mono and bis-chalcone derivatives via Claisen-Schmidt condensation reaction between arylaldehydes and ketones and 4-hydroxycoumarins and 4-hydroxy-2-quinolinones derivatives.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.
