Quality Control

Our Ir-775 Chloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and spectrophotometry to verify optical properties. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and performance. Allow the sealed container to reach room temperature before opening to prevent condensation.
