Description

3-Indoleacetic Acid, Stable Isotopes is a labeled derivative of the essential plant hormone indole-3-acetic acid (IAA), where specific atoms have been replaced with stable isotopes such as carbon-13 or deuterium. This product is critical for advanced research and analytical applications requiring precise molecular tracking and quantification. It is primarily utilized by scientists and manufacturers in the fields of plant physiology, agricultural chemistry, and pharmaceutical development for use as an internal standard in mass spectrometry and other tracer studies.

Application

• Internal Standard for Mass Spectrometry (MS): Provides accurate quantification of endogenous IAA in complex biological matrices like plant tissues.
• Metabolic Pathway Tracing: Used in stable isotope labeling experiments to study the biosynthesis, transport, and degradation pathways of auxins in plants.
• Pharmaceutical Research: Serves as a labeled precursor or reference compound in the development and analysis of related bioactive molecules.
• Environmental Fate Studies: Enables tracking of synthetic auxin analogs and their metabolites in soil and water systems.
• Quality Control & Method Development: Essential for validating analytical methods (e.g., LC-MS/MS, GC-MS) in commercial and regulatory laboratories.

Quality Control

Our stable isotope-labeled products are manufactured and analyzed under stringent conditions to ensure the highest isotopic and chemical purity. Each batch is characterized using advanced techniques including NMR and High-Resolution Mass Spectrometry (HRMS) to confirm isotopic enrichment and positional labeling. A comprehensive Certificate of Analysis (COA) detailing chemical purity, isotopic purity (atom % excess), and analytical methods is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C or as specified on the label or COA. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to maintain stability.
