Extract fentanyl from matrix patch
Hi. Can any one pls. Inform me, if isopropyl (99%) is well chosen, in attempt to extract fentanyl from matrix patch? Or should I make an effort to track down methanol? still have great trouble getting rid of the last bit of adhicive/glue from sticky side. When solution is filteret, still some trace of gum, in crystal,on glass surface, when scraping w.razorblade,
It seems,as the remaining glue (even the small amount left, after rubbing) gets ....disolved in the initial isopropyl solvent. Only after either,deluting with alkohol (Vodka +80 proof) or saline solution, the damn rubber/adhicive returns.!?
Im on my 5th trail with isopropyl extraction. Have 75mcg matrix from Mylan. Says " 12,6 mg fentanyl " Then I also have, (lucky,I know) Orion 100mcg matrix. Says "20,4 mg fentanyl ". As in each patch!
Does it mean, that potentialy, I could extract a yield that mirrors the ....almost double amount of mg, from Orion patches?
As u see, im new and English is not my first choise.
Thanks
