Description

4,4'-Azoxyanisole-D14, 96 Atom % D is a deuterated isotopologue of the liquid crystal compound 4,4'-azoxyanisole, where 96% of the hydrogen atoms have been replaced with deuterium. This high isotopic enrichment is critical for applications requiring precise spectroscopic and structural analysis, as it minimizes signal interference from protons. This labeled compound is primarily utilized by researchers and manufacturers in the fields of advanced materials science, analytical chemistry, and nuclear magnetic resonance (NMR) spectroscopy.

Application

• As an internal standard or tracer in quantitative mass spectrometry (MS) and gas chromatography-mass spectrometry (GC-MS) for method development and validation.
• For NMR spectroscopy studies, where deuterium labeling is used to simplify complex proton spectra and investigate molecular structure, dynamics, and interactions in liquid crystalline phases.
• In materials research as a deuterated model compound for studying the phase behavior and properties of liquid crystals without interference from proton signals.
• For mechanistic studies in organic and physical chemistry, tracing reaction pathways and kinetic isotope effects.
• In the development of specialized optical and electro-optical devices where deuterated compounds can offer improved stability or performance.
