Diethyl zinc

Diethyl zinc is an organozinc compound with the molecular formula (CH3CH2)2Zn and CAS number 557-20-0. It is supplied as a clear, colorless liquid with a metallic purity exceeding 99.9999% zinc, indicating exceptional elemental purity. The compound is highly pyrophoric and must be handled under inert atmosphere, making its purity critical for controlled reactions in catalysis and semiconductor manufacturing.

This material is typically synthesized via organometallic exchange reactions and purified by fractional distillation under nitrogen. Standard impurities include diethyl mercury, zinc oxide, and residual solvents, all of which are minimized in high-purity grades. The absence of visible particulates or haze confirms low particulate contamination, a key indicator of quality in semiconductor-grade applications.

It is used as a precursor in MOCVD for zinc oxide thin films, as a catalyst in asymmetric synthesis, and in the production of organozinc reagents for pharmaceutical intermediates. Buyers include electronics manufacturers, academic research labs, and fine chemical producers. Packaging is in sealed glass ampoules or stainless steel cylinders under argon. Trade terms are FOB Hangzhou, with MOQs starting at 100 grams for ampoules and 1 kg for bulk cylinders. Lead times are 10 to 20 days depending on order size and safety documentation.
