Description

Octadecatrienoic Acid Methyl Ester Labeled With Carbon-13 is a high-purity, isotopically labeled chemical standard essential for advanced analytical research and method development. Its core value lies in providing a stable, defined internal reference for precise quantification and metabolic pathway tracing in complex biological and chemical matrices. This product is critically needed by researchers and quality control laboratories in the pharmaceutical, nutritional science, and agrochemical industries, where accurate analysis of fatty acid derivatives is paramount.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference in GC-MS and LC-MS analyses of fatty acid methyl esters (FAMEs) and related compounds.
• Metabolic Tracer Studies: Enables the tracking of fatty acid metabolism, biosynthesis, and degradation pathways in biological systems using 13C-NMR or MS.
• Method Development & Validation: Serves as a critical component in developing and validating new analytical methods for lipidomics and metabolomics.
• Pharmaceutical Research: Supports drug discovery and development research involving lipid-based formulations or fatty acid-related metabolic disorders.
• Nutritional & Food Science Analysis: Used in the accurate quantification and profiling of specific polyunsaturated fatty acids (PUFAs) in food products and supplements.
• Quality Control & Assurance: Acts as a certified reference material (CRM) to ensure the accuracy and precision of in-house analytical testing for fatty acid content.

Quality Control

Every batch of our Carbon-13 Labeled Octadecatrienoic Acid Methyl Ester is manufactured and tested under strict quality management systems. We guarantee high isotopic purity and chemical purity through advanced analytical techniques including NMR, GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing the isotopic enrichment, chemical assay, and impurity profile to ensure it meets the exacting standards required for research and analytical applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon). Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. Store away from strong oxidizing agents.
