Penguinone, or to give it its full name 3,4,4,5-tetramethylcyclohexa-2,5-dien-1-one, is an organic compound. It is easy to see why it was renamed in the first instance but the name Penguinone is actually derived from the compound's molecular structure which has a striking resemblance to that of a Penguin.The suffix -one and C=O double bond indicate that Penguinone is a ketone. Ketones tend to absorb strongly in the infra-red spectrum and their peaks are determined by the other constituents of the particular ketone being analysed. To identify ketones in analytical chemistry, Carbon Nuclear Magnetic Resonance Spectroscopy is often the most effective method. For labs using NMR, Peak's hydrogen gas generators can supply parahydrogen generators to enhance magnetic resonance (MR) signals of target molecules in NMR analysis.Penguinone is also a dienone meaning its molecular structure is suitable for dienone phenol rearrangement.
