Description

Maleic-2,3-D2 Acid CAS NO 24461-33-4 is a deuterium-labeled isotopologue of maleic acid, where two hydrogen atoms at the 2 and 3 positions are replaced by deuterium. This isotopic labeling is critical for applications requiring precise molecular tracking and analysis, such as in mechanistic studies and spectroscopic investigations. It is an essential material for researchers and manufacturers in the fields of pharmaceutical development, analytical chemistry, and advanced material science.

Application

• As an internal standard in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) analysis.
• For tracer studies in metabolic and pharmacokinetic research within pharmaceutical development.
• In the synthesis of deuterium-labeled polymers and specialty chemicals for material science applications.
• As a key intermediate for producing labeled compounds in organic and medicinal chemistry research.
• For mechanistic studies in chemical reaction pathways, leveraging kinetic isotope effects.
• Use in spectroscopic calibration and as a reference material in analytical laboratories.
