Description

Decahydronaphthalene-D18 is a fully deuterated isotopologue of decahydronaphthalene (decalin), where all hydrogen atoms are replaced by deuterium. This high-purity deuterated solvent is essential for nuclear magnetic resonance (NMR) spectroscopy, providing a signal-free background for analyzing solute molecules. It is a critical material for researchers and quality control laboratories in pharmaceutical development, organic chemistry, and advanced materials science who require precise, interference-free spectral data.

Application

• NMR Spectroscopy Solvent: Primary application as a deuterated lock solvent for 1H, 13C, and other NMR experiments, offering excellent solubility for a wide range of organic compounds.
• Pharmaceutical Research & Development: Used in structural elucidation, reaction monitoring, and purity assessment of active pharmaceutical ingredients (APIs) and intermediates.
• Polymer & Materials Science: Employed in the analysis of polymer structures, kinetics of polymerization reactions, and characterization of novel organic materials.
• Academic & Industrial R&D: Serves as a standard deuterated solvent in synthetic chemistry labs for mechanistic studies and compound identification.
• Metabolomics and Biomolecular NMR: Utilized in sample preparation for complex biological mixture analysis where a non-interfering solvent matrix is required.
• Chemical Reference Standard: Acts as an internal standard or reference compound in quantitative spectroscopic methods and method development.

Quality Control

Our Decahydronaphthalene-D18 is produced and handled under strict quality management protocols. Each batch is analyzed to ensure high isotopic purity and chemical purity suitable for sensitive spectroscopic applications. Certificates of Analysis (COA) detailing isotopic enrichment (Atom % D), chemical purity by GC, water content, and NMR spectral data are provided with every shipment to guarantee traceability and compliance with your research specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its deuterated nature, minimize exposure to atmospheric moisture to maintain isotopic purity.
