Description

1-Decane-D21-Thiol is a deuterated analog of 1-decanethiol, where all hydrogen atoms are replaced by deuterium (D). This compound is a critical tool in advanced research, enabling precise mechanistic studies and analytical method development through isotopic labeling. It is primarily utilized by scientists in the fields of organic chemistry, materials science, and analytical research for applications such as NMR spectroscopy, mass spectrometry, and reaction kinetics. The high isotopic purity and defined structure make it an essential standard for specialized investigations.

Application

• NMR Spectroscopy: Serves as an internal standard or a deuterated solvent additive for chemical shift referencing and quantitative analysis.
• Mass Spectrometry: Used as a stable isotope-labeled internal standard for the accurate quantification of thiols and related compounds via GC-MS or LC-MS.
• Reaction Mechanism Studies: Employed in kinetic isotope effect (KIE) experiments to elucidate reaction pathways and transition states in organic and organometallic chemistry.
• Polymer Science Research: Acts as a chain-transfer agent or surface modifier in the study of polymerization mechanisms and the development of deuterated polymers.
• Analytical Method Development: Provides a high-purity reference material for calibrating instruments and validating analytical methods for sulfur-containing compounds.
• Surface Chemistry & Self-Assembled Monolayers (SAMs): Used to create deuterated thiolate monolayers on gold and other surfaces for studies using techniques like sum-frequency generation (SFG) spectroscopy.
