| | 1-PYRENEBUTYRIC ACID Usage And Synthesis |
| Chemical Properties | Pale yellow or yellow-beige crystalline powder | | Uses | 1-Pyrenebutyric Acid is a fluorescent probe used to study proteins, lipids, nucleic acids and other biological systems. The fluorescence lifetime of 1-Pyrenebutyric Acid depends on local oxygen and fr
ee radical concentration. | | Uses | 1-Pyrenebutyric Acid is a fluorescent probe used to study proteins, lipids, nucleic acids and other biological systems. The fluorescence lifetime of 1-Pyrenebutyric Acid depends on local oxygen and free radical concentration. | | General Description | 1-Pyrenebutyric acid (PBA) is a conjugated polymer that has a large π system and a carboxylic group. It is majorly used in surface functionalization. It has a high fluorescence efficiency and stability that make it useful in optoelectronic applications. | | Purification Methods | Crystallise the butyric acid from *benzene, EtOH, EtOH/water (7:3 v/v) or *C6H6/AcOH. Dry it over P2O5. [Chu & Thomas J Am Chem Soc 108 6270 1986, Beilstein 9 IV 2731.] |
