Description

Diphenylacetylene-D 10 is a deuterated isotopologue of the classic organic building block, diphenylacetylene (tolane). This deuterium-labeled compound is essential for advanced research and development where isotopic tracing is required. It is particularly valuable for scientists in the fields of organic synthesis, materials science, and analytical chemistry. The incorporation of deuterium atoms provides a critical tool for mechanistic studies and spectroscopic analysis.

Application

• Deuterated Internal Standard for quantitative analysis via Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR).
• Mechanistic Probe in organic and organometallic reaction studies to track reaction pathways.
• Precursor for Labeled Materials in the synthesis of deuterated polymers, liquid crystals, or pharmaceutical intermediates.
• Spectroscopic Studies, serving as a model compound for vibrational (IR, Raman) and NMR spectroscopy due to its defined isotopic label.
• Academic and Industrial R&D for developing new catalytic systems and novel organic transformations.
