Description

Methane (D1) CAS NO 676-49-3 is a high-purity, isotopically labeled form of methane, where the carbon atom is the stable isotope carbon-13 (¹³C). This compound is essential for advanced research and analytical applications where precise molecular tracing is required. It is a critical tool for scientists and engineers in the pharmaceutical, environmental science, and metabolic research sectors who require definitive tracking of carbon pathways in complex chemical and biological systems.

Application

• As a tracer gas in environmental studies to monitor atmospheric methane sources and sinks.
• In nuclear magnetic resonance (NMR) spectroscopy as a ¹³C-labeled standard for instrument calibration and complex molecular structure elucidation.
• For metabolic pathway analysis in pharmaceutical and biochemical research to track drug metabolism and nutrient utilization.
• In the development and validation of breath analyzers and medical diagnostic tests.
• As a precursor in the synthesis of other ¹³C-labeled fine chemicals and intermediates for research.
• Used in geochemical research to understand microbial methane production and consumption.

Quality Control

Every batch of our Methane (D1) is produced and analyzed under stringent conditions to ensure exceptional isotopic and chemical purity, meeting the exacting requirements of research and analytical applications. We provide comprehensive Certificates of Analysis (COA) detailing isotopic enrichment (typically >99 atom % ¹³C), chemical purity, and verification of identity. Our quality systems are designed to support GLP (Good Laboratory Practice) and research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its gaseous and highly volatile nature, store in a certified gas cylinder or appropriate sealed vessel at room temperature (15-25°C) in a well-ventilated area, away from sources of ignition and incompatible materials.
