Description

Disodium Deuterium Phosphate is a deuterated inorganic salt, where hydrogen atoms in the phosphate group are replaced by the stable isotope deuterium. This compound is valued for its role as a non-radioactive isotopic tracer and a critical reagent in nuclear magnetic resonance (NMR) spectroscopy and mechanistic studies. It is essential for researchers and manufacturers in the fields of analytical chemistry, pharmaceuticals, and advanced materials science who require precise isotopic labeling.

Application

• NMR Spectroscopy: Used as an internal standard or lock solvent component for deuterium NMR studies.
• Isotopic Labeling: Serves as a source of deuterium in synthetic pathways for mechanistic investigation and metabolic studies.
• Pharmaceutical Research: Employed in the development and analysis of deuterated drug compounds to study pharmacokinetics.
• Analytical Chemistry: Acts as a buffer component in specialized LC-MS and other analytical methods requiring deuterated environments.
• Chemical Synthesis: Utilized as a precursor or catalyst in reactions where proton/deuterium exchange is critical.
• Academic & Industrial R&D: Fundamental reagent for research in physical chemistry, biochemistry, and material science.
