Description

Hexamethylphosphoric Triamide-D18 is a deuterated isotopologue of the versatile polar aprotic solvent hexamethylphosphoramide (HMPA). This deuterated form is essential for advanced analytical and research applications where isotopic labeling is required to eliminate background interference or to study reaction mechanisms. It is particularly valuable for nuclear magnetic resonance (NMR) spectroscopy as a deuterated solvent, as well as for specialized organic synthesis and materials science research where precise isotopic control is critical.

Application

• Deuterated NMR solvent for high-resolution spectroscopy in organic chemistry and pharmaceutical research.
• Reaction medium and co-solvent in specialized organic synthesis, particularly for reactions sensitive to proton interference.
• Isotopic tracer in mechanistic studies to elucidate reaction pathways and kinetics.
• Component in the formulation of specialty electrolytes for advanced battery research.
• Solvent for polymerization reactions and the processing of high-performance polymers and fibers.
• Reagent in photochemical and electrochemical research applications.

Quality Control

Our Hexamethylphosphoric Triamide-D18 is produced and handled under strict quality protocols to ensure high isotopic purity and chemical integrity, suitable for sensitive analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D-atom %), chemical purity, and solvent residue levels. We adhere to relevant industry standards for high-purity deuterated solvents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and moisture absorption.
