Description

Pyrazine-D4 is a deuterated isotopologue of pyrazine, where four hydrogen atoms are replaced by deuterium atoms. This high-purity labeled compound is essential for advanced analytical and research applications where precise molecular tracking and minimal background interference are critical. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and material science industries for applications such as NMR spectroscopy and mass spectrometry.

Application

• Internal standard for quantitative analysis by Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Deuterated solvent for Nuclear Magnetic Resonance (NMR) spectroscopy to study molecular structure and dynamics.
• Precursor in the synthesis of deuterium-labeled active pharmaceutical ingredients (APIs) for drug metabolism and pharmacokinetics (DMPK) studies.
• Tracer molecule in chemical reaction mechanism studies and catalytic research.
• Component in the development of organic electronic materials, such as semiconductors and light-emitting diodes (LEDs).
• Reference standard for flavor and fragrance analysis due to its structural relation to key aroma compounds.
