no experience with it…but certainly hear that CBDA does crystallize. rather surprised THC doesn’t, but that’s probably why I’m not a chemist…
A purified cannabidiol (CBD) extract and/or cannabidiolic acid (CBDA) extract is isolated from industrial hemp and comprises less than 0.5 wt % organic impurities as measured by HPLC and 1H NMR spectroscopy exhibits no detectable peak at 4.07 ppm as measured by 1H NMR spectroscopy. The CBD and/or CBDA extract is in crystalline form.
Have we decided whether post processing crude to be THC free still leaves the OP with “crude”? I can’t see how it does.
Is it relevant? Not sure about that either. @Mendeleaf?!?
maybe it’s thc free Erl?
