STRUCTURAL & ISOTOPIC PROFILE
Deuterated 4-Fluorostyrene-d₃ is an isotopologue of 4-fluorostyrene in which three hydrogen atoms are replaced by deuterium (²H, D). This replacement significantly alters its spectroscopic and mass spectrometric behavior while maintaining identical chemical reactivity to the unlabeled parent compound.
This isotopic variation enables:
-
Distinct mass spectral peaks, simplifying quantification and forensic differentiation.
-
Minimal kinetic isotope effects in many reactions, enabling faithful surrogate behavior for mechanistic studies.
-
Deuterium tracer applications in metabolic, polymerization, and degradation pathways.
