Description

Thiourea-13C-15N2 is a high-purity, isotopically labeled compound where the carbon atom is enriched with the 13C isotope and both nitrogen atoms are enriched with the 15N isotope. This product is essential for advanced research and analytical applications requiring precise isotopic tracing and quantification. It is primarily used by scientists and quality control professionals in the pharmaceutical, agrochemical, and environmental analysis sectors for mass spectrometry, NMR spectroscopy, and metabolic pathway studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis for drug metabolism and pharmacokinetics (DMPK) studies.
• Metabolic Pathway Tracing: Employed in biomedical and biochemical research to track the metabolic fate of thiourea and related compounds in biological systems.
• NMR Spectroscopy: Serves as a valuable probe in nuclear magnetic resonance studies due to its distinct 13C and 15N signals, aiding in structural elucidation.
• Environmental Analysis: Utilized as a tracer in studies investigating the environmental degradation and transport of thiourea-based chemicals.
• Pharmaceutical Impurity Profiling: Acts as a labeled standard for the accurate identification and quantification of impurities and degradants in active pharmaceutical ingredients (APIs).
• Agrochemical Research: Applied in the development and analysis of isotopically labeled pesticides and herbicides for regulatory and environmental studies.
