Apremilast

This Apremilast (CAS 608141-41-9) is offered at HPLC purity ≥99.5% with enantiomeric excess ≥99.0%, and the listing references patents (including WO2016141503 and CN104761484A) covering a stable, solvate-free Crystal Form II of the compound, suggesting this may be a specific polymorph. Shanghai Utopharm, acting as a trading supplier rather than the manufacturer, distributes it under in-house standards at Pharmaceutical Grade to North and Central/South America, Western and Eastern Europe, Asia, and the Middle East.
