Does this look like a Delta 10 peak beside the delta 8 peak? Does anyone know of any labs testing d10?
CBD, methanol and KOH?
It was a Cbd conversion to delta 8

I think the unmarked large peak is d8, the small one to left is actually d9, and the one marked as d9 is just an unknown.

Agreed. There’s little to no d10 present. Maybe to the far right

I thought that too, but usually D8 is clear pink not red.
ProVerde tests for Delta 10 (exo-THC)

Exo-THC is another cannabinoid in fact.

Expecting D10 to be solid if its the dominant cannabinoid.
We’re happy to run it on the HPLC for our standard 18 cannabinoid potency test and also run it on the LC-MS/MS on our THC isomers test (including exo, D6, D8, D8 THCV, D9, D10).

Very interesting…Chris Hudalla and Jon Pogroni from ProVerde both told me that they are synonymous. I’m personally not a chemist and I could very well be incorrect. I would personally like to learn what the difference between the two cannabinoids are.
Chemical Formula: C21H30O2
Molecular Weight: 314.46

Molecular Weight: 314.5

Upon further research I have found that despite having the same Chemical Formula and basically the same molecular weight I’ve noticed a minor difference in the chemical structure. I’m guessing this is the difference?
Chris is great.
I have a janky batch of D8 going out (intentionally messed up to achieve tons of isomers/randos)to him soon that should help with his THC isomer side project.
I am very excited to see what we get back.

Maybe they or you confused some terms… happens with all these delta, iso, R stuff…
There are all isomers, same formula, same weight, but slightly different structures.
This is mainly about the position of a double bond, and in some cases the rotation of some groups.
Look here is delta 9, whit the numbered carbone:
Delta-9-THC is a short for delta9-10-THC. (where the double bond is)
Exo-THC is actually the delta9-11-THC.
And dealing with delta10, there can be two variants depending if the bond between 9 and 11 is in the same direction of that with proton at 6a or not.
This is also the case for for the 6a-10a isomers.

what is turn around time?
Thank you @Dr_Jebril
One of our chemists explained this to me in a similar fashion about a year ago, but there was still some debate at our round table over whether Exo-THC and D10 THC were synonymous. With further research and your explanation, it helps me understand much better. Thanks for your time to lay it out for me.

You cant identify an unknown just because how a peak “looks”
Run a d10 standard, compare retention times to your unknown. Even then it could be something other than d10 - HPLC is not confirmatory analysis

That is disappointing to hear. I read a comment a few weeks ago that Pro-Verde was finally getting a D10 standard but Exo-THC and D10 THC are not the same at all as you’ve discovered.
Last presentation on this page is a link to the info we (VSW Remediation) have put out on the ID of d10.
I’m sure exo-THC is worth testing for as well
