The major difference will be that the benzamidine hydrochloride hydrate (Product No. B6506) is expected to dissolve easier in aqueous solutions. Neither Product 12072 nor the salt Product B5606 is molecular biology, cell culture or biotechnology certified, so their performance once dissolved is likely to be similar.
