Description

4,4'-Dihydroxydiphenyl-D8 (Rings-D8) is a deuterated derivative of 4,4'-dihydroxydiphenyl (bisphenol A precursor), where all eight hydrogen atoms on the aromatic rings are replaced with deuterium (D). This high-purity, isotopically labeled compound is essential for advanced analytical and research applications where precise molecular tracking is required. It serves as a critical internal standard and precursor in the development and validation of analytical methods, particularly in mass spectrometry and NMR spectroscopy, for industries focused on material science, polymer research, and pharmaceutical development.

Application

• As a deuterated internal standard for the accurate quantification of bisphenol A and related phenolic compounds via LC-MS/MS and GC-MS.
• In NMR spectroscopy as a solvent or chemical shift reference to study molecular structures and dynamics without proton interference.
• For metabolic and environmental tracer studies, enabling the detailed tracking of compound degradation pathways and fate.
• As a specialized monomer or precursor in the synthesis of deuterated polymers and advanced materials for research in photonics and electronics.
• In pharmaceutical research for drug metabolism and pharmacokinetics (DMPK) studies to improve analytical method robustness.
• Use in academic and industrial R&D for mechanistic studies in organic chemistry and catalysis.
