Description

Indole--D5-3-Acetic--D2 Acid CAS NO 1173020-21-7 is a high-purity, deuterium-labeled analog of indole-3-acetic acid (IAA), a key plant hormone. This stable isotope-labeled compound is essential for precise quantitative analysis in mass spectrometry-based research, eliminating interference from endogenous compounds. It is primarily used by analytical chemists, plant biologists, and agrochemical researchers in advanced metabolic and pharmacokinetic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference standard in LC-MS and GC-MS analysis of endogenous plant auxins.
• Metabolic Pathway Tracing: Used in stable isotope labeling experiments to study the biosynthesis, transport, and degradation pathways of indole-3-acetic acid in plants.
• Phytochemical Research: Enables accurate measurement of IAA concentrations in complex plant tissue matrices for developmental and stress response studies.
• Agrochemical Development: Facilitates the analysis of plant growth regulator residues and their metabolites in environmental and crop samples.
• Isotope Dilution Analysis (IDA): Provides high-accuracy quantification in method development and validation for regulatory and quality control laboratories.

Quality Control

Every batch of Indole--D5-3-Acetic--D2 Acid is manufactured under strict quality management systems. We guarantee high chemical and isotopic purity, verified by advanced analytical techniques including NMR, HPLC, and Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic enrichment, and solvent content is provided with each shipment to ensure traceability and compliance with your research protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a cool, dry place. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
