Description

4-Oxo-2,2,6,6-Tetramethylpiperidine-D17 is a deuterium-labeled analog of the well-known nitroxyl radical precursor, 4-oxo-TEMPO. This high-purity isotopically labeled compound is critical for advanced research and analytical applications where precise molecular tracking is required. It is primarily utilized by scientists and manufacturers in the fields of organic synthesis, polymer chemistry, and analytical method development.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a crucial quantitative reference standard in LC-MS and GC-MS analysis for the accurate measurement of its non-deuterated counterpart and related compounds.
• Mechanistic Studies in Organic Synthesis: Used as a deuterium-labeled probe to investigate reaction mechanisms, kinetics, and pathways in catalytic and radical processes.
• Polymer Science Research: Employed in the study of polymerization mechanisms, polymer degradation, and the behavior of stabilizers and antioxidants within polymer matrices.
• Metabolic Tracing and NMR Spectroscopy: Acts as a stable isotope label for metabolic pathway studies and as a shift reference or probe in deuterium NMR spectroscopy.
• Pharmaceutical Impurity Profiling: Utilized in the development and validation of analytical methods for identifying and quantifying impurities and degradants in active pharmaceutical ingredients (APIs).
• Material Science: Applied in the research of advanced materials, including spin-labeling for electron paramagnetic resonance (EPR) studies on surfaces and interfaces.
