Quality Control

Our Poly[[9-(1-Octylnonyl)-9H-Carbazole-2,7-Diyl]-2,5-Thiophenediyl-2,1,3-Benzothiadiazole-4,7-Diyl-2,5-Thiophenediyl] is produced under controlled conditions to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous analytical testing, including GPC for molecular weight distribution, NMR for structural confirmation, and elemental analysis. Certificates of Analysis (COA) detailing purity, molecular weight (Mn, Mw), and polydispersity index (PDI) are provided with every shipment to support your R&D and quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C to -10°C under an inert atmosphere (argon or nitrogen) to prevent oxidation and thermal degradation. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture condensation. Keep away from heat and ignition sources.
