Quality Control

Our 4,8-Bis(2-Ethylhexyl)Benzo[1,2-B:4,5-B']Dithiophene is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, essential for reproducible device performance. Each lot is analyzed using advanced techniques including HPLC, NMR, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from heat, sparks, and open flame. Due to its light-sensitive and easily oxidized nature, prolonged exposure to air and light should be avoided.
