These are only used on two posts depicting personification of various organic compounds. All the aforementioned chemicals have been described in the annotated post #884176. Those are just images of girls, without the image of the respective structure or formula as well.
In context of imageboard, I don't think there's a chance of people coming here to find specific name of chemicals, thus those are not useful keyword. For such, we already have chemistry to cover such topic, or chemical structure.
In case in the future we may have a post depicting a vial containing nitric acid or a bottle labelled "xylene", using chemicals is just enough. We are not Wikipedia or Pubchem.
It feels weird to request BUR to nuke very small "niche" tags, but I had better let the moderation team to decide.
