The ability to characterize these moderately complex substances from powder diffraction data allows for a better understanding of their crystal chemistry. For Acitretin (54757-46-9), the transition between dimers and catamers represents a significant shift in molecular arrangement that must be monitored during the production of oral retinoid therapies.
Acitretin is a second-generation retinoid and a metabolite of etretinate. While effective for severe psoriasis, its physical properties are highly dependent on the crystallization process. Because different crystalline structures (polymorphs) can change the drug’s solubility and shelf-life, precise characterization is essential for regulatory compliance and patient safety ( ResearchGate ). 2.
