Dihydrorhodamine 123 dihydrochloride is the HCl salt form of dihydrorhodamine 123 and is functionally equivalent to the latter. However, dihydrorhodamine 123 dihydrochloride is more water soluble and more stable to air oxidation than dihydrorhodamine 123. Thus, dihydrorhodamine 123 dihydrochloride is easier to use and can be stored longer than dihydrorhodamine 123.
