Description

n-Octadecyl-D37 Alcohol is a deuterium-labeled analog of stearyl alcohol, where 37 hydrogen atoms are replaced with the stable isotope deuterium. This high isotopic purity makes it an essential internal standard and tracer in advanced analytical chemistry and metabolic research. It is primarily used by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries for quantitative analysis using techniques like mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Critical for accurate quantification in LC-MS and GC-MS analysis of lipids, surfactants, and related compounds.
• Metabolic Pathway Tracing: Used in pharmacokinetic and metabolic studies to track the fate of stearyl alcohol and its derivatives in biological systems.
• NMR Spectroscopy Solvent & Reagent: Serves as a deuterated reagent or shift reference in nuclear magnetic resonance experiments.
• Pharmaceutical Research & Development: Employed in the development and validation of analytical methods for drug substances and excipients.
• Material Science Research: Used to study the behavior, stability, and interactions of long-chain alcohols in polymers and surface coatings.
• Chemical Synthesis Intermediate: Acts as a labeled building block for the synthesis of more complex deuterated compounds.

Quality Control

Our n-Octadecyl-D37 Alcohol is produced and tested under strict quality management protocols. Each batch is characterized to ensure high chemical and isotopic purity, with key parameters verified by NMR, MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and identity confirmation is provided with every shipment to ensure traceability and compliance with your research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
