Presentation at ACS Spring 2022 conference. Recently, there has been a flood of cannabidiol (CBD)-containing products, with divers marketing claims for a plethora of use cases. With this new market segment, regulatory oversight is still developing, and label claims of CBD concentration is often verifiable. CBD is unstable in solution and some CBD products are anecdotally reported to turn purple on storage; however, the decomposition products of CBD are mostly unknown. Delic Lab embarked on a long and painstaking hunt for those decomposition products, established their identity through complementary chemical methods and established reaction pathways between them. We will present our findings about common CBD oxidation products, who those are highly photochemically unstable and decomposes rapidly. Decomposition leads to a multitude of new cannabinoid derivatives.
