• **Catalyst / co‑catalyst** — Ullmann‑type C–N/C–O/C–S
couplings; CuAAC click chemistry source of Cu(I).
• **Electronics** — p‑type semiconductor; HTL for perovskite/LEDs; TCO/paste additive. • **Iodide scavenger / reagent** — process and analytical uses. |
• 25 kg fiber drums or HDPE drums, lined.
• 1 kg bottles / foil pouches for R&D & electronics. • Custom small vacuum packs (electronic grade). |
• Protect from light/air; store cool, dry, tightly closed.
• May discolor tan due to iodine; does not affect assay if controlled. • Separate from acids/oxidizers; follow SDS PPE. Non‑DG for transport. |
