Description

Acetylene-D2 CAS NO 1070-74-2 is a deuterated analog of acetylene, where the hydrogen atoms are replaced by deuterium (²H or D). This isotopic labeling makes it a critical compound for advanced research and analytical applications, providing a non-radioactive tracer for mechanistic studies. It is primarily utilized by researchers and manufacturers in the fields of spectroscopy, organic synthesis, and materials science who require precise isotopic purity for their experimental protocols.

Application

• NMR Spectroscopy: Used as an internal standard or a deuterium source for solvent locking and shimming due to its distinct spectral properties.
• Mechanistic Reaction Studies: Serves as a tracer in catalytic and organic synthesis reactions to elucidate reaction pathways and kinetics.
• Fourier-Transform Infrared (FTIR) Spectroscopy: Employed in gas-phase studies for calibration and as a reference compound due to its well-characterized IR absorption bands.
• Isotope Labeling in Synthesis: A key starting material for the preparation of more complex deuterated organic compounds and pharmaceuticals.
• Materials Science Research: Used in the synthesis and study of deuterated polymers and advanced materials where hydrogen/deuterium isotope effects are investigated.
• Analytical Standard: Acts as a high-purity reference standard in gas chromatography and mass spectrometry for method development and calibration.
