Description

Naphthalene-13C10 CAS NO 219526-41-7 is a stable isotope-labeled analog of naphthalene, where all ten carbon atoms are the carbon-13 isotope. This high-purity compound is essential for applications requiring precise internal standards and advanced analytical tracing. It is primarily used by research institutions, analytical laboratories, and pharmaceutical developers engaged in metabolic studies, environmental analysis, and quantitative mass spectrometry.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference standard in GC-MS and LC-MS analysis for accurate measurement of unlabeled naphthalene and related compounds.
• Metabolic Pathway Tracing: Used in biomedical and pharmacological research to elucidate the metabolic fate and degradation pathways of polycyclic aromatic hydrocarbons (PAHs).
• Environmental Analysis: Enables precise tracking and quantification of naphthalene pollutants in complex matrices such as soil, water, and air samples.
• Isotope Dilution Analysis (IDA): Provides the highest accuracy method for determining naphthalene concentrations in various samples, crucial for regulatory compliance and quality control.
• NMR Spectroscopy: Acts as a valuable probe in nuclear magnetic resonance studies due to its distinct 13C signature, aiding in structural and kinetic research.
• Pharmaceutical Impurity Profiling: Assists in the identification and quantification of naphthalene-related impurities or degradation products in drug substances and products.

Quality Control

Our Naphthalene-13C10 is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥99 atom % 13C), chemical purity (by HPLC), and confirming identity via spectroscopic methods. We adhere to rigorous in-house standards designed for research and analytical use, with traceability and data integrity as core commitments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are securely sealed when not in use to prevent sublimation and potential contamination.
