Description

Daidzein-D4 is a high-purity, isotopically labeled internal standard essential for precise quantitative analysis in mass spectrometry. This deuterated compound is critical for ensuring analytical accuracy and reliability in research and quality control environments. It is primarily used by analytical chemists and researchers in pharmaceutical development, clinical diagnostics, and food safety testing who require uncompromised data integrity for their LC-MS/MS methods.

Application

• Quantitative Analytical Internal Standard: Used as a critical reference compound in Liquid Chromatography-Mass Spectrometry (LC-MS/MS) for the accurate quantification of daidzein and related isoflavones in complex matrices.
• Pharmaceutical & Pharmacokinetic Research: Enables precise tracking of daidzein absorption, distribution, metabolism, and excretion (ADME) studies in drug development and clinical trials.
• Clinical Diagnostic Assays: Serves as a stable isotope-labeled standard in diagnostic kits and laboratory-developed tests (LDTs) for measuring phytoestrogen levels in human serum, plasma, or urine.
• Nutraceutical & Food Analysis: Essential for validating and quantifying isoflavone content in soy-based products, dietary supplements, and functional foods to ensure label claim accuracy and compliance.
• Metabolomics and Biomarker Discovery: Facilitates high-fidelity identification and quantification of daidzein metabolites in large-scale metabolomic profiling studies.
• Quality Control & Method Validation: Provides a reliable benchmark for developing, validating, and auditing analytical methods in contract research organizations (CROs) and quality control laboratories.
