Quality Control

Our 1-(4-Bromo-1-Naphthyl)Hydrazine, Hcl is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and batch-to-batch consistency suitable for research and scale-up. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, purity, and impurity profiles.

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 hygroscopic nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and decomposition.
