Description

Ammonium-D8 Sulfate is a stable isotope-labeled compound where the hydrogen atoms in the ammonium ion are replaced by deuterium (D). This high-purity material is essential for applications requiring precise molecular tracking and quantification without isotopic interference. It is primarily utilized by research scientists and analytical laboratories in the pharmaceutical, environmental, and life science sectors for advanced spectroscopic and mass spectrometric analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference standard in LC-MS and GC-MS analysis for accurate measurement of ammonium or sulfate ions in complex matrices.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Used as a deuterated agent or solvent shift reagent in NMR studies to elucidate molecular structure and dynamics.
• Metabolic Pathway Tracing: Employed in stable isotope labeling studies to track nitrogen and sulfur assimilation in biological and environmental systems.
• Pharmaceutical Research & Development: Facilitates drug metabolism and pharmacokinetics (DMPK) studies by acting as a non-radioactive tracer for active pharmaceutical ingredients (APIs) and metabolites.
• Environmental Analysis: Used in isotope dilution methods to accurately determine ammonium and sulfate concentrations in water, soil, and air samples.
• Chemical Reaction Mechanism Studies: Acts as a probe in mechanistic chemistry to investigate reaction pathways involving ammonium ions.
