Description

2,7-Di(Methyl-D3)Naphthalene is a deuterated isotopologue of 2,7-dimethylnaphthalene, where the hydrogen atoms in the methyl groups are replaced by deuterium (D). This high-purity, isotopically labeled compound is critical for applications requiring precise internal standards and minimal background interference in analytical techniques. It is primarily utilized by research scientists and quality control laboratories in the pharmaceutical, agrochemical, and advanced materials sectors for method development and quantitative analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a stable, non-interfering reference compound for the accurate quantification of dimethylnaphthalene isomers and related polycyclic aromatic hydrocarbons (PAHs) in complex matrices.
• Pharmaceutical Research & Metabolism Studies: Used as a tracer in pharmacokinetic, pharmacodynamic, and drug metabolism studies to track the fate of drug molecules and their metabolites.
• Environmental Analysis: Employed in the analysis of environmental samples for PAH contamination, enabling high-precision calibration and recovery calculations.
• NMR Spectroscopy Solvent & Reagent: Acts as a deuterated solvent or reagent in nuclear magnetic resonance (NMR) spectroscopy to avoid signal overlap from protons.
• Polymer & Material Science Research: Used in mechanistic studies of polymerization and degradation processes where tracking specific molecular fragments is essential.
• Geochemical Tracing: Applied in petroleum and fuel analysis as a labeled standard for identifying and quantifying specific hydrocarbon biomarkers.

Quality Control

Every batch of our 2,7-Di(Methyl-D3)Naphthalene is manufactured and tested under strict quality management systems. We guarantee high chemical and isotopic purity, with comprehensive analysis performed using techniques including NMR, GC-MS, and HPLC. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity (typically ≥98% chemical purity, ≥99 atom % D), and conformity to your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after opening to prevent degradation.
