What’s the optimal solvent system for Reb D crystallization?
Ethanol-water (65:35 v/v) at 45°C yields 92-95% pure Reb D crystals (confirmed by HPLC-ELSD), with controlled cooling at 0.3°C/min to prevent inclusion of Reb M impurities which co-crystallize above 0.5°C/min.This article was published on March 20, 2026, and last updated on March 20, 2026.
