Quality Control

Our 4-Bromo-3,5-Dimethylphenylisothiocyanate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for research and development applications. We provide comprehensive analytical data including HPLC purity, identity confirmation (IR, NMR), and impurity profiling. Certificates of Analysis (COA) are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
