Description

Benzophenone-Carbonyl-13C is a stable isotope-labeled derivative of benzophenone, where the carbonyl carbon is enriched with the 13C isotope. This precise labeling is critical for applications requiring high-sensitivity detection and accurate metabolic or mechanistic pathway tracing. It is an essential tool for researchers and quality control specialists in the pharmaceutical, agrochemical, and advanced material sectors who rely on mass spectrometry and NMR spectroscopy for analysis.

Application

• As an internal standard in quantitative mass spectrometry (LC-MS, GC-MS) for pharmaceutical bioanalysis and pharmacokinetic studies.
• For metabolic pathway elucidation and tracer studies in biochemical and environmental research.
• In NMR spectroscopy as a chemical shift reference or for studying reaction mechanisms and molecular interactions.
• Use in quality control and method development for the analysis of benzophenone and related compounds.
• As a labeled starting material or intermediate in the synthesis of 13C-labeled complex molecules for research and development.
• Application in material science research, particularly in photochemical studies and polymer science where isotopic labeling is required.
