Essence of Smurf reappears

Diazo compounds mentioned here.

I obtained a beautiful blue compound by steam distilling the tar after a (failed?) phenol nitrosation. While the first thing to steam distill was yellow, the next batch gave something entirely different. I suspect this can be a diazo compound formed by reacting p-nitrosophenol with excess sodium nitrite.

Not the same as chemplayer's essence of smurf. I will add a link to his bitchute vid if I get a chance.
IIRC it was something of a toxic brew and definitely not something to treat carelessly.

IIRC most nitroso compounds are blue. You could just be looking at something like 3-nitroso-p-benzoquinone monoxime?

That could well be. If there’s any identification reaction you'd like me to perform on it, please go ahead by all means.

For the time being, I let the compound dry in a cool, ventilated place away from sunlight. Sunlight which tends to discolour the compound into a blue/green/grey tinge (cf. picture). I suspect very few solid will come out of it, at most a few mg.

Perhaps its indophenol blue. Try reducing the blue you have to see if it compares to the color of reduced indophenol blue below.

Interesting. I’ll try reducing it using sodium sulfite. Thanks for chiming in!
