Quality Control

Our 2,5-Diiodotoluene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Every lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. We provide a Certificate of Analysis (COA) with each shipment, detailing all critical specifications. Our quality commitment aligns with cGMP principles where applicable, ensuring the material meets the stringent requirements of pharmaceutical and advanced chemical synthesis.

Storage

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