Both products are the same catalyst, but in different forms. Product 669032 is a powder, while 685143 is the catalyst in tablet form. A specific amount of catalyst (2μmol for 685143) is impregnated into an inert tablet matrix as a time-saving alternative to weighing out the catalyst. More information on the ChemDose tablets is found at:
