Description

Potassium Octadecanoate-D35 is a deuterium-labeled form of potassium stearate, a key metallic soap and surfactant. This high-purity, isotopically enriched compound is essential for advanced analytical and research applications where precise molecular tracking is required. It is primarily utilized by scientists and manufacturers in the pharmaceutical, chemical research, and material science industries for use as an internal standard, tracer, or in mechanistic studies.

Application

• Analytical Internal Standard: Used in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) for the accurate analysis of stearate derivatives and related compounds.
• Metabolic Pathway Tracing: Serves as a deuterium-labeled tracer in biochemical and pharmacological research to study lipid metabolism, absorption, and degradation pathways.
• Polymer & Material Science Research: Employed in the study of soap-stabilized emulsions, polymer additives, and surface modification processes where isotopic labeling is needed.
• Pharmaceutical Development: Acts as a critical reference standard in the development and validation of analytical methods for drug substances and excipients.
• Chemical Synthesis Intermediate: Used in the synthesis of other deuterium-labeled complex molecules for research purposes.
