Description

Ethyl Oleate-D5 is a deuterium-labeled analog of ethyl oleate, a fatty acid ester widely used as a solvent and penetration enhancer. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry (MS) and gas chromatography-mass spectrometry (GC-MS) analysis, ensuring high accuracy and reproducibility in research. It is primarily utilized by analytical laboratories, pharmaceutical R&D teams, and contract research organizations (CROs) involved in lipidomics, pharmacokinetic studies, and metabolic research.

Application

• Internal Standard for Quantitative Analysis: Serves as a critical reference standard in GC-MS and LC-MS/MS methods for the accurate quantification of endogenous ethyl oleate and related lipid species in biological matrices.
• Metabolic Pathway Tracing: Used in deuterium-labeling studies to investigate lipid metabolism, absorption, and distribution in preclinical and clinical research.
• Pharmaceutical R&D: Supports drug development programs where precise measurement of fatty acid esters or their metabolites is required for pharmacokinetic (PK) and pharmacodynamic (PD) studies.
• Biomarker Research: Enables the reliable detection and quantification of lipid-based biomarkers in disease state studies, such as those related to metabolic disorders.
• Quality Control in Nutraceuticals: Applied in the analysis of oil-based supplements and formulations to ensure product consistency and label claim verification.
• Forensic and Doping Control Analysis: Utilized in specialized testing protocols that require high-precision isotope dilution techniques.

Quality Control

Our Ethyl Oleate-D5 is manufactured under strict quality systems to ensure the high chemical and isotopic purity required for analytical applications. Each batch is characterized by NMR, MS, and HPLC to confirm identity, deuterium incorporation, and purity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (e.g., D5 ≥ 98%), chemical purity (typically ≥95% by HPLC), and analytical data is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. For long-term storage, keep the sealed vial at -20°C. Allow the product to equilibrate to room temperature before opening to prevent moisture condensation.
