Quality Control

Our production of 1,2-Benzenediol, 4-[(1E)-2-(4-Pyridinyl)Ethenyl]- (9Ci) adheres to stringent internal quality protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR). A Certificate of Analysis (COA) detailing batch-specific results is provided to ensure traceability and compliance with your research or production requirements. We support development projects with custom purity grades and analytical support.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original container. Keep away from strong oxidizing agents.
