6-apb impurities

[till101]

hi,
what could be the impurities in the mainly available 6-apb ? as it is not white, but tan brwon, their must be some impurities in.
so what could that be ? any toxic chemical maybe ?

Presumably 1-(benzofuran-6-yl)-2-propanone and/or 1-(benzofuran-6-yl)-1-propene. Perhaps the corresponding beta-nitropropene as well.

The tan or brown colour is more than likely due to the ubiquitous "amorphous brown tar" rather than one specific impurity.

 

[till101]

are they toxic in any way ?

 

[FlippingTop]

I very much doubt that the slight impurities are doing you more harm than the 6-apb.

It's hard to say without running even a TLC on it

I would just try to recrystallize it then wash it
