Description

4,4'-Isopropylidenedi-2,6-Xylenol-D6 is a deuterated isotopologue of the common antioxidant and polymer intermediate, 4,4'-isopropylidenediphenol (Bisphenol A). This compound is specifically engineered for advanced research and analytical applications where isotopic labeling is required. It serves as a critical internal standard or tracer in mass spectrometry and NMR studies, enabling precise quantification and metabolic pathway analysis. This high-purity material is essential for scientists in pharmaceutical development, environmental analysis, and polymer chemistry research who require the highest level of accuracy and reliability in their deuterium-labeled reference compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterated internal standard for the accurate quantification of Bisphenol A and related phenolic compounds in complex matrices via LC-MS or GC-MS.
• Metabolic Tracing Studies: Employed in pharmaceutical and toxicological research to trace the metabolic fate and biotransformation pathways of bisphenol compounds.
• NMR Spectroscopy Solvent & Reagent: Acts as a deuterated agent or probe in nuclear magnetic resonance spectroscopy for structural analysis and reaction monitoring.
• Polymer Science Research: Utilized in the study of polymerization kinetics, degradation mechanisms, and additive migration in polycarbonates and epoxy resins where isotopic labeling is necessary.
• Environmental Analysis: Supports high-accuracy monitoring and fate studies of bisphenol analogs in environmental samples (water, soil, biota).
• Quality Control & Method Development: Serves as a certified reference material (CRM) for validating analytical methods in quality control laboratories.
