Description

Methyl Decanoate-D19 is a deuterium-labeled analog of methyl decanoate, a fatty acid methyl ester, where nineteen hydrogen atoms are replaced by deuterium. This high isotopic purity compound is critical for applications requiring non-radioactive isotopic tracing and internal standardization in mass spectrometry. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and analytical chemistry sectors for precise quantitative analysis and metabolic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of endogenous fatty acids or related compounds.
• Metabolic Pathway Tracing: Used in deuterium-labeling studies to track the absorption, distribution, metabolism, and excretion (ADME) of lipids and fatty acid derivatives.
• Pharmaceutical Research: Employed in the development and validation of bioanalytical methods for drug candidates that interact with lipid pathways.
• Nutritional Science Studies: Facilitates research into fat metabolism, bioavailability of dietary fats, and the role of specific fatty acids.
• Chemical Synthesis Intermediate: Acts as a labeled building block for the synthesis of more complex deuterated molecules for research purposes.
• Quality Control & Method Development: Essential for calibrating instruments and developing robust analytical methods in contract research organizations (CROs) and testing labs.
