Description

D2, 98% is a high-purity isotopic form of deuterium gas, a stable, non-radioactive hydrogen isotope. This product is essential for applications requiring precise isotopic labeling, offering distinct physical and chemical properties compared to standard hydrogen. It is a critical material for research and development in analytical chemistry, semiconductor manufacturing, and advanced materials science. The compound is supplied with a guaranteed minimum purity of 98% and is identified by CAS No. 27572-46-9.

Application

• Nuclear Magnetic Resonance (NMR) Spectroscopy: Used as a locking and shimming agent in NMR spectrometers, particularly in solvents like deuterated chloroform (CDCl3) or dimethyl sulfoxide (DMSO-d6).
• Semiconductor Fabrication: Employed in the chemical vapor deposition (CVD) and etching processes for producing silicon-based and compound semiconductor devices.
• Tracer Studies & Chemical Synthesis: Serves as a stable isotopic tracer in kinetic studies and for synthesizing deuterium-labeled compounds for research in pharmaceuticals and agrochemicals.
• Fusion Energy Research: Acts as a primary fuel component in experimental magnetic confinement and inertial confinement fusion reactors.
• Analytical Standards: Used to calibrate mass spectrometers and other analytical instruments that measure hydrogen isotope ratios.
• Optical Fiber Production: Utilized in manufacturing processes to modify the refractive index profile of glass fibers.
