Quality Control

Our 1-(1-Bromoethyl)-4-Methylbenzene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature and reactivity, it is recommended to store under an inert atmosphere for long-term preservation.
