Description

Indoleacetic Acid-D4 is a stable isotope-labeled analog of the essential plant hormone indole-3-acetic acid (IAA). This high-purity deuterated compound serves as a critical internal standard for precise quantitative analysis in mass spectrometry-based methods. It is indispensable for researchers and quality control laboratories in the agrochemical, pharmaceutical, and plant biology sectors who require accurate measurement of endogenous auxin levels, metabolic studies, and method validation.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative reference standard in LC-MS/MS and GC-MS analysis of endogenous indoleacetic acid in complex biological matrices.
• Plant Hormone Research: Enables precise tracking and quantification of auxin metabolism, transport, and signaling pathways in plant science studies.
• Agrochemical Development: Used in the research and quality control of plant growth regulators and herbicides to study their effects on auxin biosynthesis and degradation.
• Pharmaceutical Metabolism Studies: Facilitates stable isotope dilution assays (SIDA) for investigating compounds with indole-related structures in pharmacokinetic and metabolic research.
• Method Development & Validation: Critical for developing, calibrating, and validating highly sensitive analytical methods in compliance with Good Laboratory Practice (GLP).
• Environmental Analysis: Assists in the detection and quantification of natural and synthetic auxins in environmental samples.
