50 g. of finely ground mhrb was extracted 3x with 200 mL
acidic solution (800 mL 2H2O w/ 25 mL 28% muriatic).
Combined extracts (cherry red in color) were combined and
buchnered, then placed in fridge to await further processing.  over the course of a couple of days, a fair amount of particulate matter fell out of solution.  what
might this stuff be?  is it safe to filter? boingo's friend assumes the nn-DMT will stay in solution, but wants to make sure.
thanks!

peace,

Maybe also some polymeric oxidation products and stuff of low solubility that falls out on cooling. But you're right, the tryptamines should stay in solution. They are a bit unstable there, but a few days (- weeks) in that acidic solution in the fridge should be ok.

How unstable is `a bit unstable'

The stability of tryptamines depends on many factors:

- free base or a salt (usually salts are stable)
- pH of a solution (extremes are to be avoided)
- degree of amino substitution (tryptamine < N-Methyl-tryptamines < N,N-dimethyltryptamines (bases) )
- I also think that impurities affect stability, but don't ask me which ones

But as I said, a few days to weeks in the fridge should be ok.
