Description

Deuterium Hydride is a specialized isotopic compound where hydrogen is replaced by its heavier, stable isotope, deuterium. This unique composition makes it an essential reagent in advanced research and industrial processes requiring precise isotopic labeling and tracing. It is primarily utilized by the semiconductor, nuclear, and analytical chemistry sectors for applications ranging from thin-film deposition to neutron moderation and spectroscopic studies. Deuterium Hydride CAS NO 13983-20-5 offers a critical material for innovation in high-tech manufacturing and fundamental science.

Application

• Semiconductor Manufacturing: Used as a precursor gas in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for creating deuterated thin films, which can improve the electrical performance and reliability of microelectronic components.
• Nuclear Industry: Serves as a neutron moderator and coolant in certain types of nuclear reactors and research facilities due to deuterium's lower neutron absorption cross-section compared to protium.
• Analytical Chemistry & Spectroscopy: Employed as a crucial standard and reagent in Fourier-transform infrared (FTIR), nuclear magnetic resonance (NMR), and mass spectrometry for method calibration, solvent displacement, and isotopic tracing studies.
• Organic Synthesis & Pharmaceuticals: Acts as a deuterium source for the synthesis of deuterium-labeled pharmaceutical compounds, enabling detailed metabolic and pharmacokinetic studies (DMPK) in drug development.
• Fundamental Research: Essential in physics and chemistry research for studying kinetic isotope effects, reaction mechanisms, and the properties of materials at the atomic level.
• Specialty Lighting & Lasers: Used in the filling of gas-discharge lamps and certain laser tubes to produce specific spectral lines or to modify discharge characteristics.

Quality Control

Our Deuterium Hydride is produced and handled under stringent quality management protocols. Each batch undergoes rigorous analysis to ensure compliance with specified purity grades, from research-grade to ultra-high purity levels suitable for semiconductor fabrication. Certificates of Analysis (COA) detailing isotopic purity, gas composition, and impurity profiles (e.g., HD, H2, moisture, oxygen) are provided and traceable to international standards.

Storage

Preserve in a tightly closed, specially designed high-pressure cylinder or container, protected from light and stored in a cool, well-ventilated area. Due to its highly volatile and gaseous nature, cylinders must be secured upright and kept away from heat sources, open flames, and oxidizing agents. Storage temperature should not exceed 50°C (122°F). Use appropriate safety cabinets or dedicated gas storage rooms with proper ventilation and leak detection.
