Description

1,2-Ethane-D4-Dithiol is a deuterated derivative of ethanedithiol, a versatile dithiol compound where all four hydrogen atoms on the ethane backbone are replaced by deuterium. This isotopic labeling makes it an essential tool in advanced research and analytical chemistry, providing a stable, non-radioactive tracer for mechanistic studies and spectroscopic analysis. It is particularly valuable for scientists and industries requiring precise molecular tracking in complex chemical and biological systems.

Application

• As a deuterated standard or internal reference in Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) for quantitative analysis.
• In mechanistic studies and kinetic isotope effect (KIE) research to elucidate reaction pathways in organic and organometallic chemistry.
• As a specialized building block for synthesizing deuterium-labeled polymers, ligands, or pharmaceutical intermediates.
• In materials science for the development of labeled self-assembled monolayers (SAMs) or surface modification agents.
• For the preparation of isotopically labeled chelating agents in coordination chemistry and catalysis research.

Quality Control

Our 1,2-Ethane-D4-Dithiol is produced and handled under strict quality protocols to ensure high isotopic purity and chemical integrity. Each batch is supported by comprehensive analytical data, including NMR for deuterium enrichment and chromatographic methods for chemical purity. A Certificate of Analysis (COA) detailing isotopic purity (D-enrichment), chemical assay, and impurity profile is available upon request to meet rigorous research and development standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, prolonged exposure to air and elevated temperatures should be avoided. Recommended storage temperature is 2-8°C.
