Description

Toluene (Methyl-13C) CAS NO 6933-23-9 is a stable isotope-labeled analog of toluene, where the methyl carbon is the carbon-13 isotope. This product is essential for advanced analytical and research applications requiring precise molecular tracing and quantification. It is primarily used by researchers and quality control laboratories in the pharmaceutical, environmental, and chemical synthesis industries for use as an internal standard in mass spectrometry and NMR spectroscopy.

Application

• Internal standard for quantitative analysis by Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Tracer compound in metabolic pathway studies and pharmacokinetic research.
• Reference material for NMR (Nuclear Magnetic Resonance) spectroscopy for chemical shift calibration and method development.
• Critical component in environmental analysis for detecting and quantifying toluene and its derivatives in complex matrices.
• Starting material or intermediate in the synthesis of isotope-labeled complex molecules for research and diagnostic purposes.
• Quality control and method validation in pharmaceutical laboratories to ensure analytical accuracy and regulatory compliance.

Quality Control

Our Toluene (Methyl-13C) is produced and handled under strict quality protocols to ensure the highest isotopic and chemical purity for sensitive analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and solvent content. We adhere to relevant standards for high-purity reference materials to guarantee reliable and reproducible performance in your laboratory.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration change. Recommended storage temperature is 2-25°C.
