Sphingosine (d17:1) (C17 Sphingosine) is a 17-carbon sphingolipid found in human skin that can be phosphorylated by sphingomyelin kinase.Sphingosine C-17 can be used as an internal standard to perform spectroscopic analysis of sphingolipids.

(Glu2)-TRH, a metabolically stable analogue of Thyrotropin-releasing hormone (TRH), is a negative modulator for the cholinergic effect of TRH in the mouse brain. (Glu2)-TRH significantly attenuates TRH-induced hippocampal extracellular acetylcholine release. (Glu2)-TRH is not metabolized by thyroliberinase. (Glu2)-TRH manifests neuroprotective, antidepressant, anticonvulsant in the CNS.

2-Acetylthiazole is used in the preparation of chiral alcohols, triazolothiazoles, it is also used in aldol condensation reactions.
