This week’s substance is gloriously complex. My source for the composition included the compound 2-Ethyl-1-hexanol which may be a degradation product from plasticisers which may have come from labware. To this end I have not included the structure of this compound below. Nor have I included the structure of the 20 other small molecules that may be present in this substance. I think there’s sufficient below to figure it out! Apologies also for the unpaired ions – its safe to assume that there are counterions present within the substance, either the organic acids or other stuff like chloride that wasn’t included in the analytical data.
Below I’ve listed the key chemicals or elements found in a commonly available product, which may be slightly UK-centric. All chemicals drawn below are part of the same product. I’ve drawn the chemical structures of principal components where simple and appropriate; given the E number or CAS number (however tempting Sigma-Aldrich catalogue numbers would be) if no simple chemical structure exists for an additive; and given the chemical formulae or name if neither of the above make sense. See if you can guess what this is! If no one gets it within 24 hours, I will post a clue. If you guess on Twitter (@kjhaxton), please DM your guess so others can play.
