Description and Uses
1-Thioglycerol is a reagent used in fluorescence, spectroscopy, and microbiology techniques. Varying the concentration of 1-thioglycerol in the preparation of CdSe/CdS core-shell ultrasmall quantum dots (CS-USQDs) allows a precise way to control the size of the shell, with shell size increasing with increased concentration. It is used as a capping agent in the synthesis of nanocrystals analyzed via Raman and UV/Vis spectroscopy. Biologically, 1-thioglycerol stimulates porphyrin synthesis and increases glutamyl-tRNA reductase activity in E. coli grown in an aerobic environment. It was previously a component in hair permanents used to produce waves or curls.
It generally used as a size-regulating capping agent for nanocrystals. 1-Thioglycerol is also used in bacteriology experiments to induce the synthesis of porphyrin compounds in aerobically growing Escherichia coli. Also used to study the pH-sensitive photoluminescence of aqueous thiol-capped CdTe nanocrystals. 1-Thioglycerol is used to develop and test thiol functionalized copolymers. 1-Thioglycerol is used as a post-modification agent in the generation of non-standard peptide foldamers.Potential substitute for 2-mercaptoethanol, probe for the study of lymphocyte activation.
