Description

Diphenyl-3,3',4,4',5,5'-D6 is a deuterated isotopologue of biphenyl, where six hydrogen atoms at the 3, 3', 4, 4', 5, and 5' positions are replaced with deuterium. This isotopic labeling is critical for applications requiring minimal spectral interference, as it provides a stable, non-radioactive tracer with distinct spectroscopic properties. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for use as an internal standard in mass spectrometry, NMR spectroscopy, and in the study of metabolic pathways and reaction mechanisms.

Application

• Internal Standard for Quantitative Analysis: Serves as a high-purity internal standard in LC-MS and GC-MS for the accurate quantification of biphenyl and related compounds in complex matrices.
• NMR Spectroscopy: Used as a deuterated solvent or shift reference in nuclear magnetic resonance studies to eliminate proton signal interference.
• Metabolic & Pharmacokinetic Studies: Acts as a stable isotopic tracer in drug metabolism and disposition (DMPK) research within pharmaceutical development.
• Mechanistic Reaction Studies: Employed in deuteration experiments to elucidate reaction mechanisms and kinetic isotope effects in organic and organometallic chemistry.
• Polymer & Materials Science: Used in the synthesis and analysis of deuterated polymers and advanced materials for neutron scattering experiments.
• Environmental & Forensic Analysis: Functions as a labeled standard for the detection and tracing of biphenyl derivatives in environmental and forensic samples.
