Description

Diphenyl-4-D1 is a deuterated aromatic compound where a hydrogen atom at the 4-position of one phenyl ring is replaced by a deuterium atom (CAS NO 4819-98-1). This isotopic labeling provides a stable, non-radioactive tracer that is critical for advanced analytical and research applications. It is an essential building block for scientists and manufacturers requiring precise molecular tracking in complex systems. Key industries that utilize this specialty chemical include pharmaceutical research, agrochemical development, and materials science for mechanistic studies and metabolic pathway analysis.

Application

• Pharmaceutical Research: Used as an internal standard in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for accurate quantification of drugs and metabolites.
• Metabolic Studies: Serves as a stable isotopic tracer to investigate drug metabolism, pharmacokinetics, and biochemical pathways without radioactive hazards.
• Agrochemical Development: Employed in the synthesis of deuterated pesticide analogs for environmental fate studies and residue analysis.
• Organic Electronics: Acts as a precursor for deuterated materials, where the incorporation of deuterium can enhance the lifetime and performance of organic light-emitting diodes (OLEDs).
• NMR Spectroscopy: Provides a valuable probe in nuclear magnetic resonance (NMR) spectroscopy for structural elucidation and reaction monitoring due to its distinct spectroscopic signature.
• Chemical Mechanism Elucidation: Utilized in kinetic isotope effect (KIE) studies to reveal detailed reaction mechanisms in organic and organometallic chemistry.
