Quality Control

Our Crotyl Bromide Tech. 85 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, identity, and impurity profile. We are committed to meeting the specifications and reliability standards required by our global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent degradation. Keep away from strong bases and incompatible materials.
