WebRubber Oligomeric Compounds? All pharmaceutical butylrubbers (butyl, chlorobutyl, bromobutyl) do contain the C13H24 and C21H40 oligomers as impurities. Extractable and subsequent leachable studies have revealed, in certain cases, that C13H24 and C21H40 oligomers may leach out of the rubber into the drug product. WebSpecifically, the improved butyl rubber compound is produced by mixing into the rubber an organic isocyanate and an aromatic dinitroso compound or an aromatic dioxime. Any organic isocyanate may be used in the practice of this invention.
