What solvents can be used to dissolve Benzamidine, Product 12072?
Based on our experience with this compound in quality control, we would expect it to be soluble in methanol (0.5g in 10mL of methanol).
The buffer preparation protocol calls for benzamidine. Should I use the free base or the hydrochloride hydrate salt?
It is possible that either the benzamidine or the benzamidine hydrochloride hydrate could work for your application. 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.
What is the solution stability of Benzamidine, Product 12072?
Sigma-Aldrich does not perform formal solution stability testing on this material; however, it is expected to be sensitive to oxidation. It is recommended to prepare solutions fresh for each use.
