2,4,6-Trichlorobenzoyl chloride is used in the preparation of γ-lactone and δ-lactone, aliphatic aromatic anhydrides, required for the synthesis of amphiphilic hyaluronan, mixed anhydride, required for the synthesis of angelate esters, synthesis of both spongistatin 1 and spongistatin 2 and large-ring lactones in high yields.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
