Quality Control

Our production of 3-Nitro-6,7,8,9-Tetrahydro-5H-Benzo[7]Annulen-5-One adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistent chemical identity. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming specifications for identity, assay, and impurity profiles. We support custom synthesis and purity grade requirements to meet specific research and development needs.

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 its property of being easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from heat, sparks, and open flames.
