Curious what the shelf life is of the 7, 8 dihydroxyflavone powder? I bought some about a year ago and was wondering if it is still good. Also, have you guys looked into the 5, 7 variant?

it passed NMR and assay
What is nmr? I think assay is like a machine test to see what a thing is, but no idea what nmr is.

Nuclear magnetic resonance spectroscopy. The most common is proton/hydrogen NMR. That uses a strong magnetic field to measure the resonance of the hydrogen atoms in a sample. Then you can elucidate the chemical structure by looking at the signals. You can also do other types like phosphorous or carbon-13, but hydrogen is the most common.
