Description

(E,E)-6-α-Ionylidene-4-Methylpyran-2-One-D5 is a deuterated derivative of a key ionone-related compound, specifically designed for advanced research and development applications. This high-purity, isotopically labeled standard is critical for analytical method development, metabolic studies, and internal standardization in mass spectrometry. It is primarily utilized by research institutions and industrial R&D departments in the fragrance, flavor, and pharmaceutical sectors where precise quantification and trace analysis are paramount.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a stable, non-interfering reference compound for the accurate quantification of its non-deuterated counterpart in GC-MS and LC-MS analyses.
• Metabolic Pathway Tracing: Used in pharmacokinetic and metabolic studies to track the absorption, distribution, metabolism, and excretion (ADME) of related flavor or fragrance molecules.
• Analytical Method Development: Essential for developing and validating highly sensitive and specific analytical methods in quality control laboratories.
• Fragrance & Flavor Research: Employed in the study of degradation pathways, stability testing, and authenticity verification of complex natural product mixtures.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities or degradation products in active pharmaceutical ingredients (APIs).
