Description

Phenyl-D5 Isocyanate is a deuterium-labeled isotopologue of phenyl isocyanate, where five hydrogen atoms on the phenyl ring are replaced with deuterium. This stable isotopic labeling is critical for applications requiring precise molecular tracking and analysis, offering a non-radioactive alternative for research. It is an essential building block and analytical standard for scientists in pharmaceutical development, agrochemical research, and advanced material science.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis for pharmacokinetic and metabolic studies.
• Pharmaceutical Research & Development: Serves as a labeled precursor in the synthesis of deuterated drug candidates to study metabolism, bioavailability, and degradation pathways.
• Metabolite Identification & Tracing: Enables the precise tracking of molecular fragments in complex biological systems for metabolite profiling.
• Polymer Science & Material Research: Employed in the development of specialized polyurethanes and polymers where isotopic labeling is used to study polymer dynamics, structure, and degradation.
• Agrochemical Research: Utilized in the synthesis of labeled pesticides or herbicides to investigate environmental fate, degradation, and residue analysis.
• NMR Spectroscopy: Acts as a useful reagent or standard in Nuclear Magnetic Resonance studies due to the distinct spectroscopic signature of deuterium.
