Properties and stability

Keep away from oxidizing agents and light.

Storage method

Store in an airtight container and keep refrigerated away from light. Keep away from oxidizing agents and light.

Synthesis method

Derived from the reaction of ethylene and iodine. Pour ethylene into a mixture of iodine and ethanol until the color of iodine completely disappears and needle-like crystals appear. After the reaction is completed, filter and wash, and the obtained crude product is recrystallized with ethanol to obtain 1,2-diiodoethane.

Purpose

Used in organic synthesis.
