Description

Toluene (Ring-D5) CAS NO 1603-99-2 is a deuterated derivative of toluene, where five hydrogen atoms on the aromatic ring are replaced with deuterium atoms. This isotopic labeling is critical for applications requiring non-interfering internal standards and enhanced spectral resolution in analytical techniques. It is an essential reagent for researchers and quality control laboratories in the pharmaceutical, agrochemical, and advanced materials sectors. The compound provides a stable isotopic marker for precise quantitative analysis and mechanistic studies.

Application

• Internal Standard for Quantitative Nuclear Magnetic Resonance (qNMR) spectroscopy.
• Deuterated solvent and reference compound in Mass Spectrometry (MS) and Fourier-Transform Infrared (FTIR) spectroscopy.
• Tracer molecule in metabolic and pharmacokinetic studies within pharmaceutical R&D.
• Precursor for the synthesis of other deuterated fine chemicals and Active Pharmaceutical Ingredients (APIs).
• Use in polymer research to study reaction mechanisms and polymer dynamics.
• Essential for environmental analysis as a labeled standard for detecting toluene and its metabolites.
• Component in OLED and organic semiconductor research for investigating charge transport properties.

Quality Control

Our Toluene (Ring-D5) is produced under stringent conditions to ensure high isotopic and chemical purity, meeting the exacting requirements of analytical and synthetic applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and solvent residue profiles. We adhere to a robust quality management system, and specifications can be tailored to meet specific customer or pharmacopeial guidelines upon request.

Storage

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