Description

Hexacosanoic--D4 Acid is a deuterium-labeled analog of cerotic acid, a long-chain saturated fatty acid. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy, ensuring precise and accurate analytical measurements. It is primarily required by researchers and quality control laboratories in the pharmaceutical, biotechnology, and advanced chemical synthesis sectors for metabolic studies, lipidomics, and pharmacokinetic research.

Application

• Internal Standard for Mass Spectrometry (MS): Critical for the accurate quantification of cerotic acid and related long-chain fatty acids in complex biological matrices like plasma, tissues, and cell cultures.
• Metabolic Pathway Tracing: Used in deuterium-labeling studies to investigate lipid metabolism, fatty acid elongation, and β-oxidation pathways.
• Pharmaceutical R&D: Supports drug metabolism and pharmacokinetics (DMPK) studies for compounds that interact with or are derivatives of fatty acids.
• Lipidomics Research: Enables precise profiling and quantification of lipids in nutritional, disease state, and biochemical research.
• NMR Spectroscopy: Serves as a valuable reference standard in structural analysis and mechanistic studies due to its distinct spectroscopic signature.
• Quality Control & Method Validation: Employed in analytical laboratories to validate and calibrate methods for fatty acid analysis, ensuring regulatory compliance (GMP, GLP).
• Chemical Synthesis: Acts as a labeled building block for the synthesis of more complex deuterated compounds for research purposes.

Quality Control

Our Hexacosanoic--D4 Acid is manufactured under strict quality systems to ensure high isotopic purity and chemical integrity, suitable for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity (by HPLC), and identity confirmation (by MS and NMR). We adhere to standards relevant to research and fine chemical production.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Keep the container in a cool, dry, and well-ventilated place away from incompatible materials.
