Quality Control

Our (S)-Sunphos is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is analyzed to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing specific test results are provided with every shipment. We adhere to cGMP principles where applicable to support our customers' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is easily oxidized and light-sensitive; prolonged exposure to air or light should be avoided to maintain stability and performance.
