Description

Methane-D2 CAS NO 676-55-1 is a stable isotope-labeled form of methane, where two hydrogen atoms are replaced by deuterium (²H). This deuteration is critical for applications requiring precise molecular tracking and reduced interference in spectroscopic analysis. It is an essential reagent in advanced research and industrial processes within the pharmaceutical, chemical, and analytical sectors.

Application

• NMR Spectroscopy: Used as an internal standard or solvent for nuclear magnetic resonance studies, providing a deuterium lock signal.
• Mass Spectrometry: Serves as a calibration standard and a reagent gas in chemical ionization for accurate mass determination.
• Chemical Synthesis: Employed as a deuterium source in catalytic hydrogen-deuterium exchange reactions and the synthesis of deuterated compounds.
• Fundamental Research: Utilized in kinetic studies, reaction mechanism elucidation, and isotopic tracer experiments.
• Semiconductor Manufacturing: Acts as a process gas in the deposition of deuterated carbon films and other specialized materials.
• Analytical Reference Standard: Provides a high-purity benchmark for gas chromatography and other analytical techniques.

Quality Control

Our Methane-D2 is produced and handled under stringent quality management systems. Each batch is analyzed to ensure high isotopic purity and chemical purity, with specifications typically meeting or exceeding 99% deuterium atom % D. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, purity by GC, and identity confirmation is provided with every shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Cylinders should be secured in an upright position. Due to its gaseous state, ensure containers are not subjected to physical damage or excessive temperature fluctuations.
