Quality Control

Our 1,2-Dihydrophenanthrene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical characterization, including HPLC for purity assessment and GC-MS, NMR (1H & 13C), and IR for structural confirmation and identification of impurities. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality attributes. Our production adheres to cGMP principles where applicable, ensuring suitability for demanding R&D and scale-up processes.

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). Keep away from strong oxidizing agents, strong acids, and heat sources. For long-term storage, consider storing under an inert atmosphere (e.g., nitrogen or argon) to prevent potential oxidation.
