Hydroxyurea stability

[Angela Alexander]

Does anyone know how long hydroxyurea is stable when dissolved in water, and stored in aliquots at -20?  I searched google for almost an hour and its very confusing.  Lots of information about hydroxyurea as a pharmaceutical, which says to store at room temperature basically for 1 month (ugh, is that all?).  I ordered some from Sigma to do experiments with, and it says to store at 4 degrees.  I'm going to dissolve some in water and store at -20 -- or is this not a good idea?
 
 Thanks.
