Reaction Steps
A ceftolozane sulfate composition can be obtained by a process comprising the steps of: (a) forming a solution comprising water, 72-100 g/L ceftolozane active and 1.5-2.95 molar equivalents of sulfuric acid to ceftolozane; (b) combining the solution from step (a) with 20-40 volumes of isopropyl alcohol added to the solution over 0.5-8 hours to obtain solid ceftolozane sulfate; and (c) isolating the solid ceftolozane sulfate composition from the solution.
