Description

Monobutyl Phosphate-D9 is a deuterated isotopologue of monobutyl phosphate, where nine hydrogen atoms are replaced with deuterium, a stable hydrogen isotope. This high-purity labeled compound is essential for applications requiring precise analytical tracking and minimal background interference. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors for use as an internal standard, tracer, or reagent in mass spectrometry and NMR studies.

Application

• Internal Standard for Mass Spectrometry (MS): Provides a stable, isotopically labeled reference for the accurate quantification of monobutyl phosphate and related compounds in complex matrices like biological fluids or environmental samples.
• Metabolic Pathway Tracer: Used in pharmaceutical and biochemical research to study the absorption, distribution, metabolism, and excretion (ADME) of phosphate ester-containing compounds.
• NMR Spectroscopy Solvent/Reagent: Serves as a deuterated solvent or reagent in nuclear magnetic resonance (NMR) experiments to eliminate proton signal interference and simplify spectral analysis.
• Chemical Synthesis Intermediate: Acts as a specialized building block in the synthesis of deuterated analogs of more complex molecules for research and development.
• Analytical Method Development: Critical for developing and validating highly sensitive and specific LC-MS/MS or GC-MS methods in regulatory and quality control laboratories.
