Derivative Type: Crystalline sulfates
Properties: Sol in acidic aq solns; much less sol in the neutral pH range. Generally insol in organic solvents. Both components show good stability in aq acidic solns, but are readily inactivated above pH 7.0. Commercial prepns are mixtures of both with 90% ristocetin A.
