Description

2 4-Dichlorophenoxyacetic Acid-Ring-Ul-& CAS NO 89300-30-1 is a specialized, isotopically labeled analog of the widely used herbicide 2,4-D. This compound is of critical importance for research and analytical applications, providing a stable, non-radioactive tracer for precise metabolic and environmental fate studies. It is primarily needed by agrochemical research laboratories, environmental testing facilities, and academic institutions conducting advanced analytical chemistry and mass spectrometry-based investigations.

Application

• Metabolic Pathway Tracing: Used as an internal standard in LC-MS and GC-MS analyses to study the absorption, distribution, metabolism, and excretion (ADME) of 2,4-D in plants and organisms.
• Environmental Analysis: Serves as a crucial reference standard for the accurate quantification of 2,4-D residues in soil, water, and crop samples, ensuring regulatory compliance and environmental monitoring.
• Analytical Method Development: Essential for developing and validating highly sensitive and specific analytical methods (e.g., HPLC, GC) for herbicide detection and quantification.
• Isotope Dilution Mass Spectrometry (IDMS): Employed in this gold-standard technique for achieving the highest accuracy and precision in quantitative analysis, minimizing matrix effects.
• Degradation Studies: Facilitates research into the photolytic, hydrolytic, and microbial degradation pathways of phenoxy herbicides in the environment.
• Quality Control & Assurance: Acts as a certified reference material (CRM) for calibrating equipment and verifying the accuracy of analytical results in quality control laboratories.
