Delta 10 THC

Only to the trained eye @Kingofthekush420 , it took me months to develop the right methods and comprehension of the HPLC/DAD to be able to differentiate the 2 cannabinoids. And it took GCMS and NMR testing and comparison to confirm my methods on HPLC/DAD were valid.

Given an ā€œambiguousā€ HPLC-DAD, GC-FID should get you close with a CBC (and probably THCV based on the guess my GC made) standard.

It will certainly be good enough to backup claims of ā€œbullshit! That is not CBC!ā€

Wonder if the portable FTIR could be trained to ā€œseeā€ it?

given the retention time I saw on an SRI 8610C, I suspect it will be resolvable on the SRI-420 I picked up.

Once I have a home setup for that thing Iā€™ll have to hit you up for a sample.

Mary made some delta nine,
and took it to her guy.
He turned it into delta 10,
and now she canā€™t get high.

Mary was sad,
But her guy had the answer,
ā€œItā€™s not as psychoactive,
But it could cure cancer.ā€

So can you please clarify something. Everyone this thread has been identifying CBC with d10. But when I asked earlier in the thread I was told what you produced was d10a. Which one is it? Is the title wrong?

Delta 10, not delta 10a.

We kept seeing CBC spikes when running short path even when the crude didnā€™t show any. Now that we are running a wiped film the levels are way lower but still present from the decarb. My understanding is that itā€™s THC deteriorating to CBN and just not completing the process.

I wonder if thatā€™s what happened Here to this sample using iodine as a catalyst for CBN? @Shadownaught

That ā€œCBCā€ peak is Delta 10. Iā€™m 99% positive. Just another case of mistaken cannabinoid identity.

@coppertop Iā€™m not sure if that is what is happening in that CBD distillate scenario, good theory though. I havenā€™t worked with enough CBD material to provide an accurate opinion yet. Definitely interested and if I Had access to samples Iā€™d be happy to run comparative analysis to identify if itā€™s Delta 10 or truly CBC.

Seems like heat and time will create unidentified products even without a catalyst.

ā€œThe experimental results for thedecarboxylation of CBDA are shown in Figures 5and 6. In this case, the mass balance is not as clearas the THCA-A data. In both 110Ā°C and 130Ā°C, thesum of the molar concentration of CBDA and CBD diminished as the time and temperature of the experiments increase. This indicates more complex chemistry than the stoichiometric conversion of CBDA/CBD. It might also be an indication of com-pound evaporation under vacuum condition or unidentified products produced at the higher temperature.ā€

" Likewise, Dussy also studied the decarboxylation of pure Ī”9-tetrahydrocannabinolic acid A (THCA-A), however, the generation of Ī”9-THC was maximal at an intermediate temperature (225Ā°C) but with only 65% conversion. At 300Ā°C, a significant loss of Ī”9-THC was observed, although no CBN, a possible oxidation product, was observed."

I wonder if these unidentified products are actually just d10

Yeah with 58% d8 I absolutely stand by my assertion that the cbc peak is not CBC at all, its Detla 10, like has been the case on dozens of my consults. Id put money on that.

just look at the molecule, its such a thermodynamically uphill battle to rip open thc to cbc, the whole point of the synthesis is the enzymes ciclyzing cbga into the downstream products. until your lab has a d10 standard, the point is moot

Would Cerilliant be the best folks to work with on that?

cannabinoids

check it out, CBG has one ring structure, CBC has 2, THC has three. The enzymes latch onto the carboxyllic group and close those ring structures. You just cant go backwards Every piece of evidence Ive ever seen asserts that. Prove me wrong and ill happily eat my words as I start pumping out kilos of CBC isolate.

A simple acid or media in the flask could easily push thc down its lower energy state gradient, or maybe up a little hill to get to d10, but to think that it could get pushed all the way back up to cbc, thats far fetched as far as I can tell

you can get delta8 in flower just wont ever break 1%

Mechoulam reports that d8 and d10a are these thermodynamic wells for THC. I HIGHLY recommend anyone interested in these transformations read everything Mechoulam et al published starting in the 60s.
