Description

Daidzein-D6 is a deuterium-labeled internal standard of the soy isoflavone daidzein, specifically designed for high-precision analytical applications. This stable isotope-labeled compound is essential for ensuring accurate quantification and reliable data in mass spectrometry-based assays. It is a critical tool for researchers and quality control professionals in pharmaceutical development, clinical research, and nutritional science who require uncompromised analytical integrity and traceability in their work.

Application

• Quantitative Bioanalysis: Serves as an internal standard for the accurate LC-MS/MS quantification of daidzein and its metabolites in biological matrices such as plasma, serum, and urine.
• Pharmacokinetic & Metabolism Studies: Enables precise tracking of daidzein absorption, distribution, metabolism, and excretion (ADME) in preclinical and clinical research.
• Dietary Supplement & Food Testing: Used in the quality control and standardization of soy-based products, nutraceuticals, and functional foods to verify isoflavone content.
• Endocrine & Cancer Research: Facilitates the study of daidzein's biological activity, its interaction with estrogen receptors, and its role in disease models.
• Method Development & Validation: A key component in developing and validating robust analytical methods for compliance with FDA, EMA, and other regulatory guidelines.
• Reference Material Production: Used in the preparation of certified reference materials (CRMs) and calibration standards for laboratory proficiency testing.
