Quality Control

Our Robinetin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for identification, and residual solvent analysis, to ensure it meets stringent specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We can supply material compliant with various pharmacopeial standards, including USP and EP reference standards, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider sealing under an inert gas such as nitrogen or argon to maintain stability and potency.
