Quality Control

Our 3-Bromo-4-(Methylsulfonyl)Benzaldehyde is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical specifications. We adhere to cGMP principles where applicable to support our clients' regulatory requirements.

Storage

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