Description

Imino(Diacetic-D4) Acid CAS NO 21386-66-3 is a deuterated derivative of iminodiacetic acid, where four hydrogen atoms are replaced by deuterium, a stable hydrogen isotope. This isotopic labeling is critical for applications requiring precise molecular tracking and reduced signal interference in analytical techniques. It is an essential building block and analytical standard for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors who require high-fidelity deuterated compounds.

Application

• Deuterated Internal Standards for quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) analysis in pharmaceutical and environmental testing.
• Precursor for Labeled Chelating Agents used in the synthesis of deuterated analogs of EDTA and similar complexing agents for research.
• Metabolic Pathway Tracing in biochemical and pharmacological research to study drug metabolism and biological mechanisms.
• Synthesis of Deuterated Pharmaceuticals (Deuterated Drug Candidates) to potentially improve metabolic stability and pharmacokinetic profiles.
• NMR Solvent & Reagent for use in spectroscopic studies where proton background signals must be minimized.
• Material Science Research in the development of specialized polymers and organic electronic materials where isotopic purity affects properties.
