Description

Toluene-D6 2,4-Diisocyanate is a deuterated analog of toluene diisocyanate (TDI), specifically labeled with six deuterium atoms. This compound is critical for advanced analytical and research applications where isotopic labeling is required to eliminate background interference and enhance detection sensitivity. It is primarily utilized by researchers and quality control laboratories in the polymer, pharmaceutical, and material science industries for precise spectroscopic studies, metabolic pathway tracing, and as an internal standard in mass spectrometry.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a high-purity, isotopically labeled reference standard for the accurate quantification of toluene diisocyanate in complex matrices.
• NMR Spectroscopy Studies: Serves as a crucial tool in nuclear magnetic resonance (NMR) for mechanistic studies and structural elucidation in polymer chemistry and organic synthesis.
• Metabolic and Pharmacokinetic Research: Enables precise tracking and analysis of TDI metabolites and pathways in biological systems without isotopic interference.
• Polymer Science R&D: Employed in the development and analysis of specialized polyurethane foams, coatings, and elastomers to study reaction kinetics and polymer structure.
• Environmental and Industrial Hygiene Analysis: Facilitates the sensitive and accurate monitoring of TDI exposure in workplace air and environmental samples.
• Isotope Dilution Analysis: A key component in high-accuracy analytical methods for the determination of TDI concentrations in various industrial and research samples.

Quality Control

Our Toluene-D6 2,4-Diisocyanate is manufactured under strict quality systems to ensure exceptional isotopic purity and chemical integrity. Each batch is characterized using advanced analytical techniques including NMR, GC-MS, and HPLC to confirm isotopic enrichment, chemical purity, and identity. A comprehensive Certificate of Analysis (COA) detailing isotopic purity, chemical assay, and impurity profile is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture ingress.
