Quality Control

Every batch of 2-Bromo-5-Hydroxybenzaldehyde is manufactured and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat and incompatible materials.
