Hola Mike and List The problem with the organic complex of dimethyl glyoxine is its low viability (around 1 to 2 month) in alcoholic solution, depending of the temperature ambient. Once it is dissolved (this white dust) in alcohol beginning the degradation. but the dust of dimetyl glyoxine is very stable in the time, I have a flask 3 year working very well. and every time that I need a test I meke the alcoholic solution only for the day.
