Description

1,7-Di(Methyl-D3)-Naphthalene is a deuterated derivative of naphthalene, specifically labeled on the methyl groups, with the CAS number 29636-70-2. This compound is a crucial stable isotope-labeled standard, providing unmatched precision for analytical methods requiring high specificity and minimal background interference. It is primarily required by research and quality control laboratories in the pharmaceutical, agrochemical, and advanced material science sectors for use as an internal standard in mass spectrometry, NMR spectroscopy, and metabolic studies.

Application

• Used as a stable isotope-labeled internal standard in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for accurate quantification.
• Essential in pharmaceutical research for drug metabolism and pharmacokinetics (DMPK) studies, tracing the fate of parent compounds.
• Applied in NMR spectroscopy as a tracer to elucidate reaction mechanisms and molecular structures without signal overlap.
• Utilized in environmental analysis for tracking polycyclic aromatic hydrocarbon (PAH) derivatives and their degradation pathways.
• Serves as a building block in organic synthesis for creating deuterated polymers or advanced materials with modified properties.
• Supports forensic and toxicological analysis by providing a reference for identifying specific metabolite patterns.
