Description

Elaidic-13C Acid CAS NO 201996-48-7 is a stable isotope-labeled analog of elaidic acid, a trans-isomer of oleic acid, where one or more carbon atoms are replaced with the 13C isotope. This compound is an essential tool for precise metabolic and biochemical research, enabling accurate quantification and tracing of fatty acid pathways. It is primarily required by analytical laboratories, pharmaceutical R&D departments, and academic institutions conducting advanced lipidomics, nutrition science, and drug metabolism studies.

Application

• Internal Standard for Quantitative Analysis: Used in GC-MS and LC-MS methods for the accurate quantification of elaidic acid and related fatty acids in complex biological matrices.
• Metabolic Pathway Tracing: Serves as a tracer in studies investigating the absorption, distribution, metabolism, and excretion (ADME) of trans-fatty acids.
• Biomarker Research: Employed in the development and validation of clinical assays to measure trans-fatty acid levels as potential biomarkers for dietary intake or disease states.
• Nutritional Science Studies: Facilitates research on the metabolic effects of dietary trans fats, including their impact on lipid profiles and cardiovascular health.
• Pharmaceutical Development: Used in drug discovery to study drug-lipid interactions and the role of specific fatty acids in pharmacological mechanisms.
• Quality Control Reference: Acts as a certified reference material (CRM) for calibrating analytical instruments and ensuring data integrity in testing laboratories.

Quality Control

Our Elaidic-13C Acid is manufactured under strict quality protocols to ensure high isotopic enrichment and chemical purity suitable for sensitive analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic purity (atom % 13C), chemical purity (by HPLC/GC), and identity confirmation. We support research and compliance needs with traceable documentation.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. For long-term storage, keep the container sealed in a cool, dry, and well-ventilated area. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation.
