Description

Indole-2,4,5,6,7-D5-3-Acetic Acid is a deuterated analog of the key plant hormone indole-3-acetic acid (IAA), where five hydrogen atoms are replaced with deuterium, creating a stable isotopic label. This compound is essential for advanced research requiring precise metabolic tracing and quantification in plant physiology, biochemistry, and analytical chemistry. It is primarily used by scientists and manufacturers in the agrochemical, pharmaceutical, and academic research sectors for use as an internal standard in mass spectrometry and for studying auxin biosynthesis, transport, and signaling pathways.

Application

• Internal Standard for Mass Spectrometry (MS): Provides high accuracy and precision for the quantitative analysis of endogenous indole-3-acetic acid in complex biological matrices.
• Plant Hormone Research: Used in metabolic flux studies to trace the biosynthesis, degradation, and transport pathways of auxins in plants.
• Agrochemical Development: Employed in the research and development of plant growth regulators and herbicides to understand mode of action and metabolic fate.
• Pharmaceutical Research: Serves as a tool in biochemical research related to tryptophan metabolism and its derivatives.
• Analytical Reference Standard: Certified reference material for calibrating analytical instruments and validating methods in regulatory and quality control laboratories.
• Isotope Dilution Analysis: Critical for high-precision quantification techniques that correct for analyte loss during sample preparation.
