Description

1-Dodecane-D25-Thiol is a deuterated analog of dodecanethiol, where all hydrogen atoms on the alkyl chain are replaced by deuterium (D). This high-purity, isotopically labeled compound is critical for advanced research and analytical applications where precise molecular tracking and minimal background interference are required. It is primarily utilized by scientists and engineers in the fields of pharmaceutical development, materials science, and analytical chemistry for applications such as NMR spectroscopy and mechanistic studies.

Application

• NMR Spectroscopy: Serves as an internal standard or a deuterated solvent shift reagent for structural elucidation and quantitative analysis.
• Pharmaceutical Research: Used as a labeled intermediate in the synthesis of deuterated drug candidates for pharmacokinetic and metabolic studies.
• Polymer Science: Acts as a chain-transfer agent in the controlled radical polymerization of deuterated polymers for neutron scattering studies.
• Mechanistic Studies: Employed in isotopic labeling experiments to trace reaction pathways and investigate chemical mechanisms.
• Analytical Standards: Functions as a high-purity reference standard in mass spectrometry and chromatography for method development and calibration.
• Surface Chemistry: Used to create deuterated self-assembled monolayers (SAMs) for studies on surface interactions and lubrication.

Quality Control

Every batch of 1-Dodecane-D25-Thiol is produced and analyzed under strict quality management protocols to ensure exceptional isotopic purity and chemical integrity. Our products undergo rigorous quality testing, including NMR and GC-MS analysis, to ensure compliance with customer specifications for research and development. Certificates of Analysis (COA) detailing isotopic enrichment, chemical purity, and specific test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place at temperatures between 2°C and 8°C (refrigerated). Keep away from strong bases and oxidizing agents. For long-term storage under an inert atmosphere (e.g., nitrogen or argon), please contact our technical team for specific recommendations.
