Product Name:1-Ethynyl-4-(methylsulfonyl)benzene
English Name:1-Ethynyl-4-(methylsulfonyl)benzene
CAS No.:340771-31-5
Aliases:4-Ethynylphenyl methyl sulfone, 4-(Methylsulfonyl)phenylacetylene, 1-Ethynyl-4-(methylsulfonyl)benzene
Molecular Formula:C9H8O2S
Physical Properties:Light yellow to pale brown solid at room temperature with a pungent odor. Insoluble in water; soluble in methanol, ethanol, dichloromethane, ethyl acetate and other organic solvents. Density approximately 1.2 g/cm³, boiling point approximately 315°C, flash point approximately 130°C. Stable in air but sensitive to light; recommended to be stored in the dark.
Uses:This compound, bearing both ethynyl and methylsulfonyl groups, serves as an organic synthesis intermediate. Under transition-metal catalysis, it can participate in Sonogashira coupling and click chemistry reactions to construct sulfonyl-containing aryl alkyne scaffolds, and is widely used in the synthesis of pharmaceuticals, agrochemicals, fine chemicals and functional materials.
Technical Specifications:
Formula: C9H8O2S
Molecular weight: 180.22
Purity: ≥95% (reagent grade)
Appearance: light yellow to pale brown solid
Storage: keep sealed, protected from light, stored at 2–8°C
