Description

Trimethyl-D9 Phosphate is a deuterated isotopologue of trimethyl phosphate, where nine hydrogen atoms are replaced by deuterium. This high-purity labeled compound is essential for advanced analytical and research applications where isotopic tracing and mass spectrometry are critical. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries for use as an internal standard, a stable isotope-labeled reagent, or a precursor in synthesis.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis of organophosphate compounds, metabolites, and environmental samples.
• Metabolic Pathway Tracing: Employed in pharmacokinetic and drug metabolism studies to track the fate of phosphate-containing molecules using deuterium labeling.
• NMR Spectroscopy Solvent & Reagent: Serves as a deuterated solvent or a chemical shift reference in nuclear magnetic resonance (NMR) spectroscopy.
• Synthetic Intermediate: Acts as a labeled building block for the synthesis of more complex deuterated organophosphorus compounds, pharmaceuticals, and ligands.
• Environmental Analysis: Applied in the detection and quantification of trace organophosphate flame retardants and pesticides in environmental matrices.
• Material Science Research: Used in studies involving deuterated polymers, electrolytes, or other materials where hydrogen-deuterium exchange properties are investigated.
