Quality Control

Our trans-1,4-Dibromo-1,2,3,4-Tetrahydronaphthalene is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flames. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant packaging.
