Description

Glyceryl Tri(Octanoate-8,8,8-D3) is a deuterium-labeled analog of glyceryl trioctanoate (tricaprylin), a medium-chain triglyceride. This compound is specifically designed for use as an internal standard in quantitative mass spectrometry, enabling precise and accurate analysis in complex biological and chemical matrices. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, nutritional science, and metabolic research sectors who require high-fidelity analytical standards for method development and validation.

Application

• Internal Standard for Mass Spectrometry (MS): Primary application for quantitative analysis of medium-chain triglycerides and their metabolites in LC-MS and GC-MS workflows.
• Pharmaceutical Research & Development: Used in pharmacokinetic (PK) and bioavailability studies of lipid-based drug formulations.
• Nutritional Science & Metabolism Studies: Enables precise tracking and quantification of lipid absorption, digestion, and energy metabolism in research models.
• Quality Control & Analytical Method Validation: Serves as a critical reference material for ensuring accuracy and reproducibility in the analysis of fats, oils, and lipid excipients.
• Stable Isotope Labeling Experiments: Acts as a tracer in metabolic flux analysis and lipidomics to study biochemical pathways.
• Food & Dietary Supplement Analysis: Used to assay medium-chain triglyceride (MCT) content and authenticity in finished products.

Quality Control

Our deuterated compounds are produced under strict quality protocols to ensure isotopic purity and chemical integrity, which are critical for analytical applications. Each batch of Glyceryl Tri(Octanoate-8,8,8-D3) is characterized by advanced spectroscopic and chromatographic techniques, including NMR, MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and analytical data is provided with every shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) for long-term stability. The product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions when possible. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
