Application
1. Acts as a bifunctional alkylating agent in organic synthesis for constructing four-carbon chain-containing heterocyclic compounds.
2. Serves 1 4-Diiodobutane CAS 628-21-7 as a key intermediate in the production of pharmaceutical ingredients, such as certain antitumor and antibacterial drugs.
3. Functions as a cross-linking reagent for preparing specialty polymers and ionic liquids with tailored physical and chemical properties.
Storage and Precautions
1. Store in sealed amber glass containers at 0-10℃ in a dark, dry area away from light, heat, and oxidizing substances.
2. Keep 1 4-Diiodobutane CAS 628-21-7 separated from strong bases, active metals, and reducing agents to prevent elimination reactions and iodine release.
3. Wear nitrile gloves, safety goggles, and a vapor respirator; handle in a fume hood to avoid skin contact and vapor inhalation.
What are the benfits of taking 1 4-Diiodobutane?
1. The symmetric 1,4-diiodo structure ensures high selectivity in nucleophilic substitution reactions for target molecule synthesis.
2. Excellent 1 4-Diiodobutane CAS 628-21-7 solubility in halogenated solvents like dichloromethane simplifies reaction operation and product separation.
3. Provides a precise four-carbon spacer group, which is essential for synthesizing compounds with specific molecular configurations.
Safety Information
