Quality Control

Our Phenethylzinc Bromide is manufactured under stringent quality control protocols, typically offered in research and development grades. Each batch is characterized to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing assay, impurity profile, and solution concentration (if applicable) are provided. We adhere to cGMP principles where required, and specifications can be aligned with customer-specific pharmacopeial or internal standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. For long-term stability, storage at 2-8°C is recommended. The container should be kept tightly sealed in a secondary receptacle and handled in a well-ventilated environment.
