Deletion of 4'-Hydroxy-5,7-dimethoxy-8-methylflavan

Comment: As per , multiple sources (ideally ''secondary'' sources, not primary sources like research papers) are generally expected to establish notability.  There is no policy that chemical compounds are an exception to this rule (nor is there any particular reason to have such an exception).  The whole point of the notability guideline is that ''our personal opinions'' are not the basis for inclusion in Wikipedia; rather, something is notable if |reputable sources agree that it is such.  A single academic paper does not establish notability&mdash;the question is, did the paper withstand the test of time to be accepted as correct and noteworthy in its scientific field, as evidenced by being cited (approvingly) and its conclusions (or in this case, the chemical) used repeatedly over time by other papers

Comment: If it has only been mentioned in one publication, it appears to fail . There is no inherent notability for every possible arrangement of C, H and O atoms in a molecule
