tetraloopA four-base hairpin loop motif in RNA secondary structure that caps many double helices
tetramethylbenzidineAny of several isomeric tetramethyl derivatives of benzidine, but especially 3,3’,5,5’-tetramethylbenzidine that is a chromogenic substrate used in immunohistochemistry
tetramethylcyclopropaneA chemical compound with four methyl groups connected to a cyclopropane ring.
tetramethyleneA hypothetical hydrocarbon, C₄H₈, analogous to trimethylene, and regarded as the base of well-known series or derivatives.
tetramethylenedisulfotetramineA highly toxic, colorless crystalline compound formerly used as a rodenticide in poisoned bait and now widely banned in many countries because of its extreme neurotoxicity and high risk of accidental poisoning in humans and animals.
tetramethylethylenediamineAn organic compound derived from ethylenediamine by replacement of the four N-H groups with four N-methyl. It has a fishy odour and is used as a reagent and a ligand for metal ions.
