γ-Butyrolactone
ReagentPlus®, ≥99%
| Synonym: | γ-Hydroxybutyric acid lactone, 4-Hydroxybutyric acid lactone, GBL |
| CAS Number: | 96-48-0 |
| Linear Formula: | C4H6O2 |
| Molecular Weight: | 86.09 |
| Beilstein Registry Number: | 105248 |
| EC Number: | 202-509-5 |
| MDL number: | MFCD00005386 |

Description
| Packaging | 20 kg in VerSA-Flow™ |
| 25, 500 g in glass btl | |
| 3 kg in glass btl | |
| 20 kg packaged in closed-head composite drums; 25 g, 500 g, 3 kg packaged in glass bottles | |
| Application | For the introduction of 3-carboxypropyl side chain.1 Used as a component of electrolyte solutions in batteries and capacitors.2 |
| Biochem/physiol Actions | Precursor of γ-hydroxybutyric acid (GHB). It blocks dopamine release by blocking impulse flow in dopaminergic neurons. Pretreatment with γ-butyrolactone allows detection of autoreceptor-induced dopamine release. |
