What changed
A laboratory study compared single-stage and two-stage MSMPR crystallization for paracetamol Form I and carbamazepine Form III at matched total active volume and residence time. Staging improved particle uniformity, reduced fouling, and shortened filtration times while preserving solid-state and chemical quality. The findings attribute the benefit to supersaturation distribution rather than additional crystallizer capacity.
Why it may matter
The findings support supersaturation staging as a process-development lever, with compound-specific scale-up and robustness studies needed before manufacturing adoption.
