Description

1-Octadecane-D37-Thiol is a deuterium-labeled analog of octadecanethiol, a long-chain alkanethiol. This compound is valued for its role as a stable isotopic tracer in advanced research and analytical chemistry, providing critical insights into reaction mechanisms and material properties. It is essential for scientists and engineers in the fields of surface science, materials research, and analytical method development who require high-purity, isotopically labeled standards.

Application

• As a deuterated internal standard for quantitative analysis via Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Mass Spectrometry (LC-MS).
• Surface modification and self-assembled monolayer (SAM) formation for studying surface properties and interactions with deuterium-labeled specificity.
• Research into reaction kinetics and metabolic pathways where tracking the fate of the thiol group is necessary.
• Use in the synthesis of deuterium-labeled polymers, nanoparticles, and other advanced materials for specialized characterization.
• Investigations in lubrication and tribology where labeled molecules help understand wear mechanisms and film formation.
• Development and calibration of spectroscopic methods, including NMR and IR, requiring isotopically pure references.

Quality Control

Our 1-Octadecane-D37-Thiol is produced under stringent conditions to ensure high isotopic and chemical purity, critical for research applications. Each batch is characterized by advanced analytical techniques including NMR, GC-MS, and HPLC to verify deuterium incorporation and chemical identity. Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and analytical results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and degradation. This material is easily oxidized; prolonged exposure to air should be avoided. Keep the container tightly sealed in a cool, dry, and well-ventilated place.
