 Application:
(1) GBL can be used to produce a-pyrrolidone, *-Methyl**-  
      pyrrolidinone ,polyvinyl pyrrolidone, and α-Acetyl-γ-butyrolactone, etc.
(2)GBL can be used as anaesthetic and tranquilizer, used to 
     produce ciprofloxacin and interferon, as the intermediate of vitamin  
     and rolicyprine;
(3) GBL is the intermediate of plant growth stimulator and insecticide.
(4)GBL is a good antioxidant, plasticizer, extractant, adsorbent, 
     dispersant, fixative and curing agent; Moreover, it can also be used 
     in battery,capacitor and development of color film. 
Storage and Transportation: 
Stored in cool and airy place; away from fire and heat; handle with care; no breakage, avoid leakage
