Uses

Different sources of media describe the Uses of 2365-48-2 differently. You can refer to the following data:
1. Methyl Thioglycolate is an derivative of Thioglycolic Acid (T350760), an organic compound containing both a thiol and a carboxylic acid functional groups. Thioglycolic Acid and its derivatives are oft en used in organic synthesis as a nucleophile in thioglycolysis reactions and is also used as a S transfer agent for sulfonyl chloride synthesis. Methyl Thioglycolate have been studied for the its inf luence on neocarzinostatin activation and expression of DNA damage.
2. Methyl thioglycolate was used in the preparation of 3-carbomethoxy-4- oxotetrahydrothiopyran, 2- and 4-carbomethoxy-3-oxotetrahydrothiophene. It is used to prepare methyl thioglycolate and aminoethanethiol conjugated gold nanorods.

General Description

Methyl thioglycolate reacts with nonprotein component of the antitumor antibiotic neocarzinostatin to form 1:1 adduct. It reacts with isothiocyanate to form Rhodanine.

Side-chain pairing preferences in the parallel coiled-coil dimer motif: Insight on ion pairing between core and flanking sites

A new strategy for rapid evaluation of sequence-stability relationships in the parallel coiled-coil motif is described. The experimental design relies upon thiol-thioester exchange equilibria, an approach that is particularly well suited to examination of heterodimeric systems. Our model system has been benchmarked by demonstrating that it can quantitatively reproduce previously reported trends in interhelical a-a′ side-chain pairing preferences at the coiled-coil interface. This new tool has been used to explore the role of Coulombic interactions between a core position on one helix and a flanking position on the other helix (a-g′). This type of interhelical contact has received relatively little attention to date. Our results indicate that such interactions can influence coiled-coil partner preferences.

ADDITION OF METHYL MERCAPTOACETATE TO N-VINYLPYRROLES

Methyl esters of 2-(pyrryl-1)ethylthioacetic acid were synthesized in 53-71percent yield by addition of methyl mercaptoacetate to N-vinylpyrroles.Their reactions with ammonia and hydrazine hydrate were investigated.

Method for producing methyl thioglycolate based on sodium hydrosulfide method

The invention relates to a method for producing methyl thioglycolate based on a sodium hydrosulfide method, which belongs to the technical field of organic synthesis. The method comprises the step ofdistilling and concentrating thioglycolic acid acidified liquid, and adding CaCl2 to obtain distilled and concentrated liquid containing molten salt hydrate, an esterification reaction step in which the molten salt hydrate is used as a reaction medium, and the step of settling and layering to obtain methyl thioglycolate. The separation of thioglycolic acid, the treatment of the extraction tail wastewater and the esterification reaction are integrated, the production process is greatly simplified, the water and the solid salt can be effectively separated, the content of organic matters in the water and the solid salt is low, the separated water can be recycled, and the solid salt can also be used as a byproduct. The side reaction in the production process of the methyl thioglycolate is greatly reduced, the discharge of wastewater and the dosage of a catalyst are reduced, and the resource recycling is realized.

Unusual multistep reaction of C70Cl10 with thiols producing C70[SR]5H

We report a reaction of the chlorofullerene C70Cl10 with thiols producing C70[SR]5H with all organic addends attached around one central pentagon at the pole of the C70 cage. This reaction was shown to proceed via a complicated radical pathway, presumably involving addition, substitution, rearrangement, and/or elimination steps. The obtained C70[SR]5H products were shown to be very unstable and undergo quantitative decomposition to pristine C70, RSSR, and RSH at elevated temperatures (e.g., 50 °C). Quantum chemical calculations and NMR spectroscopy data showed that cleavage of organic addends from the fullerene cage could be induced by solvation effects in solution.
