Quality Control

Our Methyl 3-Bromo-5-Formyl-4-Hydroxybenzoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize degradation.
