If sc-210759 has a purity of only ≥ 60%. What are the impurities of the remaining product?

Asked by: Chemsynth123
Thank you for your question. When Adenosine 3'-phosphate 5'-phosphosulfate lithium salt, sc-210759, decomposes impurities such as adenosine 3′,5′-diphosphate, sulfate and ammonia substitution products can form. Storing sc-210759 at -20ºC and minimizing exposure time at room temperature will prevent formation of these impurities.
