3,4-Dibromothiophene is clear colorless to yellow liquid
| [Uses]
3,4-Dibromothiophene was used in the preparation of thieno[3,4-b]thiophene. It was aslo used as starting material in the synthesis of alkyl substituted, fused thiophenes. | [Uses]
3,4-Dibromothiphene is used in the synthesis of thiophene-estrogen receptor ligands which contain superagonist activities when involving luciferase in genes in human cells giving 2-3 times the activit
y of estradiol. Also used in the synthesis of supercapacitors for use as charge storage applications. | [General Description]
Double photoionization spectra of 3,4-dibromothiophene has been investigated by coincidence spectroscopy technique based on electron time-of-flight measurement. |
