1,4-Diiodobutane(CAS: 628-21-7)

1,4-Diiodobutane (CAS: 628-21-7) is a colorless or light yellow liquid with a molecular weight of about 306.06 g/mol. It has a low solubility in water but is soluble in common organic solvents like ethanol and acetone. It is highly reactive due to the presence of iodo groups and can undergo substitution reactions. It crystallizes in a monoclinic form at low temperatures.

1,4-Diiodobutane can be synthesized via the reaction of 1,4-diiodobutene with ethylene or by the iodination of 1,4-butadiene using iodine and a suitable catalyst. The reaction typically yields a high selectivity for the 1,4-position and can be performed in good yield under controlled conditions.

1,4-Diiodobutane (CAS: 628-21-7) is used in the pharmaceutical industry for the synthesis of certain drugs, and in the polymer industry for the modification of polymers. It is also used in the production of sensors and semiconductors due to its iodo groups which can be functionalized for specific applications.

Handling 1,4-Diiodobutane (CAS: 628-21-7) requires wearing appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a fume hood to avoid inhalation. Spills should be cleaned up using appropriate absorbents and properly disposed of according to local regulations. Always consult the Material Safety Data Sheet (MSDS/SDS) for detailed safety information.
