“…Examination of the structural characteristics of SMZ, acetyl‐SMZ, and NSMZ provided clues as to how the SMPT was hindered. The single‐crystal structure of acetyl‐SMZ was found to be very similar to that of SMZ Form II 15. As clusters of SMZ Form II are formed in the slurry, it is likely that acetyl‐SMZ can substitute for a SMZ molecule in the cluster.…”
