Description

Benzophenone-2,3,4,5,6-D5 is a deuterated analog of benzophenone, where five hydrogen atoms on the aromatic rings are replaced with deuterium, a stable isotope of hydrogen. This isotopic labeling is critical for applications requiring enhanced analytical precision and reduced spectral interference, such as in NMR spectroscopy and mass spectrometry. It serves as an essential internal standard, tracer, or starting material for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high isotopic purity and chemical stability.

Application

• Used as an internal standard and reference material in quantitative Nuclear Magnetic Resonance (qNMR) and Liquid Chromatography-Mass Spectrometry (LC-MS) analyses.
• Acts as a deuterated tracer in metabolic and pharmacokinetic studies within pharmaceutical research and development.
• Employed as a labeled starting material or intermediate in the synthesis of more complex deuterated compounds for various R&D applications.
• Facilitates mechanistic studies in organic chemistry and catalysis, where deuterium labeling helps elucidate reaction pathways.
• Applied in the development and calibration of analytical instruments and methods requiring isotopically pure standards.
• Used in material science research, particularly in photophysical studies, where deuterated compounds can exhibit altered properties.
