Description

n-Docosane-D46 is a fully deuterated isotopic analog of n-docosane (a straight-chain saturated hydrocarbon with 22 carbon atoms), where all 46 hydrogen atoms are replaced with deuterium (²H). This high-isotopic-purity compound serves as a critical internal standard in quantitative mass spectrometry for accurate lipidomics, metabolomics, and environmental analysis. Its structural fidelity to native n-docosane ensures identical chromatographic behavior and ionization efficiency—enabling precise correction for matrix effects and instrument variability. It is essential for laboratories requiring trace-level quantification of long-chain alkanes in complex biological, petrochemical, and atmospheric samples.

Application

• Internal standard for GC-MS and LC-MS/MS quantification of n-docosane and related aliphatic hydrocarbons in biological matrices (plasma, tissue, feces)
• Calibration reference in environmental analysis of petroleum hydrocarbons in soil, sediment, and water samples
• Tracer compound in kinetic studies of alkane biodegradation and microbial metabolism
• Reference material for method validation and quality assurance in clinical and forensic toxicology labs
• Stable isotope dilution assay (SIDA) standard for lipid profiling in high-throughput omics platforms
• Matrix-matched calibration standard in food safety testing for hydrocarbon contaminants

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch of n-Docosane-D46 CAS NO 260411-88-9 is verified by high-resolution mass spectrometry (HRMS), ¹H NMR, and ²H NMR to confirm isotopic enrichment (>99.0 atom% D), chemical purity (>98.5%), and structural integrity. Certificates of Analysis (COA) are available upon request and include full spectral data, assay results, and impurity profiles. The product meets specifications aligned with ACS Reagent Grade and ISO/IEC 17025-accredited testing protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15–25°C) in a dry, well-ventilated area. Avoid exposure to moisture and strong oxidizing agents. Due to its light-sensitive nature, minimize handling under ambient lighting and use amber glass vials or aluminum foil-wrapped containers for long-term stability.
