Quality Control

Our 3-Bromo-5-Methylbenzaldehyde is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We are committed to meeting the stringent requirements of GMP and ISO standards for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
