Was at my cottage and I had some intermediates like petroleum ether, NaOH and potassium cyanate, and a bottle of syrup containing norephedrine hcl..
I basified the syrup, and extracted it with petroleum ether but I didn't have any funnels/ziplock-bags or any other
ghettoware to separate the layers so I thought I'll buy some ziplock-baggies from the local store and HCl from the pharmacy the next day...
Then I had emergency call and had to come back to the big city
.. I left the sealed mason jar with the NaOH/Benzene to the fridge and now comes the question:
The freebase has been sitting there for couple of weeks now and I think it has formed the carbonate from the CO2 (from air which was trapped inside the flask), but is it still usable for 4-MA synth?
I've never encountered this kind of 'question' beefore =)
