ABSTRACT:
Sulfonic acid salts, and particularly the methanesulfonic acid salt of 6-amino-1,5-dihydro-4H-imidazo-[4,5-c]pyridin-4-one (3-deazaguanine) possess unexpected solubility in water and are thus useful in preparing pharmaceutical compositions having the requisite stability, clarity, and potency for parenteral administration.
