Quality Control

Our 3,4-Dihydro-6,7-Dihydroxy-2'-Methoxyspiro[Naphthalene-1(2H),1'-Cyclohexane]-2',5'-Dien-4'-One is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support custom synthesis and can tailor purity grades (e.g., >95%, >98%, >99%) to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to the presence of phenolic dihydroxy groups, this compound may be sensitive to oxidation and should be handled under an inert atmosphere for long-term storage of pure material. Keep away from strong oxidizing agents.
