Tetrachlorophthalic anhydride, 98%, Thermo Scientific Chemicals
Supplier: Thermo Scientific Chemicals A1740436
Description
Protection of amines as their tetrachlorophthalimide derivatives, by reaction with the anhydride in the presence of triethylamine, has been found to be useful in oligosaccharide chemistry. The group is stable to a wide range of reagents but can be selectively cleaved with ethylenediamine at lower temperatures than for the parent phthalimide derivatives; in particular, carboxylic esters are not cleaved under these conditions.
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.
