Description

Ethylene-D4 is a deuterated isotopologue of ethylene, where all four hydrogen atoms are replaced by deuterium atoms (CAS NO 683-73-8). This isotopic labeling makes it an indispensable tool in advanced research and analytical chemistry, providing a non-radioactive tracer for mechanistic studies and spectroscopic analysis. It is primarily required by scientists and engineers in the pharmaceutical, agrochemical, and materials science sectors for applications in nuclear magnetic resonance (NMR) spectroscopy, reaction pathway elucidation, and the development of deuterated polymers.

Application

• NMR Spectroscopy: Used as an internal standard or solvent for high-resolution NMR studies, providing a deuterium lock signal.
• Mechanistic Reaction Studies: Acts as a tracer to investigate reaction pathways, kinetics, and intermediates in catalytic and organic synthesis.
• Deuterated Polymer Synthesis: Serves as a monomer for producing deuterated polyethylene, which is used in neutron scattering experiments to study polymer structure and dynamics.
• Mass Spectrometry: Employed as a reference standard in GC-MS and LC-MS for accurate mass calibration and quantification.
• Chemical Vapor Deposition (CVD): Used in the production of specialized thin films and semiconductor materials where controlled isotopic composition is critical.
• Fundamental Research: Essential in academic and industrial labs for studying isotope effects on chemical and physical properties.

Quality Control

Our Ethylene-D4 is produced and handled under stringent quality protocols to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % D), chemical purity, and verification of identity. We adhere to cGMP principles where applicable, and our quality system is designed to meet the exacting standards of research and development laboratories globally.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature, store in a certified gas cylinder or appropriate pressurized vessel in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container valve tightly sealed when not in use. Store at room temperature (15-25°C) in an upright position.
