Description

(±)-Glyceryl 1-Monooctadecanoate-D35 is a high-purity, deuterium-labeled analog of glyceryl monostearate, a key compound in advanced research and analytical applications. This stable isotope-labeled material is essential for precise quantification and metabolic pathway tracing in complex biological and chemical systems. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, nutritional science, and chemical synthesis sectors who require the highest standards of analytical accuracy and material traceability.

Application

• As an internal standard for the accurate quantification of glyceryl monostearate and related compounds in pharmaceutical formulations and food products using mass spectrometry (LC-MS, GC-MS).
• In metabolic studies and pharmacokinetic research to trace the absorption, distribution, metabolism, and excretion (ADME) of lipid-based excipients and active ingredients.
• For method development and validation in analytical laboratories to ensure regulatory compliance (e.g., FDA, ICH guidelines) for assay precision and accuracy.
• In deuterium-labeling synthesis to create other labeled compounds for specialized research applications.
• As a critical reagent in quality control and assurance processes for manufacturers of lipids and emulsifiers.
