Description

Nonadecanoic-D37 Acid CAS NO 1219798-8 is a high-purity, deuterium-labeled analog of nonadecanoic acid, where 37 hydrogen atoms are replaced with deuterium. This heavy isotope labeling is critical for providing an internal standard in quantitative mass spectrometry, ensuring unparalleled accuracy and reliability in analytical measurements. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, metabolomics, and environmental testing industries who require definitive quantification of fatty acids and related compounds.

Application

• Internal Standard for Mass Spectrometry (MS) & GC-MS: Primary use as a quantitative reference standard for the analysis of C19 fatty acids and their derivatives in complex biological matrices.
• Pharmaceutical Research & Drug Metabolism Studies (DMPK): Used in pharmacokinetic studies to track and quantify drug metabolites and endogenous fatty acid pathways with high precision.
• Clinical Diagnostics & Metabolomics: Enables accurate profiling of fatty acids in plasma, serum, and tissue samples for biomarker discovery and disease research.
• Lipidomics Research: Essential for the targeted quantification of nonadecanoic acid and related lipids in cellular and organismal lipidomes.
• Food & Nutritional Science Analysis: Serves as a standard in the assay of fatty acid composition in food products, dietary supplements, and oils.
• Environmental Analysis: Applied in tracing and quantifying fatty acids and organic pollutants in environmental samples.
• Stable Isotope Labeling in Chemical Synthesis: Used as a building block in the synthesis of more complex deuterated compounds for research.

Quality Control

Every batch of Nonadecanoic-D37 Acid is manufactured and analyzed under strict quality systems to ensure the highest isotopic and chemical purity required for analytical standards. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request and provide detailed data for parameters including isotopic purity (Atom % D), chemical purity (by HPLC/GC), and identity confirmation.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C or as indicated on the label or COA. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
