Product Name:(R)-2,4-diiodo-3-methylbut-1-ene
English Name:(R)-2,4-diiodo-3-methylbut-1-ene
CAS No.:481048-22-0
Aliases:2-iodo-3-(iodomethyl)but-1-ene, (R)-2,4-diiodo-3-methyl-1-butene, (R)-2-iodo-3-(iodomethyl)but-1-ene
Molecular Formula:C5H8I2
Physical Properties:Colorless to light yellow liquid with a characteristic iodohydrocarbon odor. Density approx. 2.1 g/cm³, boiling point approx. 185°C, flash point approx. 105°C. Slightly soluble in water; soluble in ethanol, diethyl ether, chloroform, dichloromethane and other organic solvents. Light-sensitive; decomposes and discolors upon exposure to light. Optically active, R configuration.
Uses:This product is a chiral building block containing two iodine atoms and a terminal alkene, widely used in organic synthesis to construct iodoalkene structural units. In pharmaceutical R&D and fine chemical synthesis, it serves as a substrate for transition-metal-catalyzed coupling reactions to introduce chiral alkene fragments. It is also used in the preparation of chiral ligands, iodinated natural product analogs, and functional material precursors.
Technical Specifications:
Molecular weight: 321.93
Purity: ≥95% (GC)
Density: approx. 2.1 g/cm³ at 20°C
Boiling point: approx. 185°C at atmospheric pressure
Storage: sealed under inert gas, protected from light at 2-8°C
