Description

(4-Chloro-2-Methylphenoxy)Acetic Acid-13C6 is a stable isotope-labeled analog of the herbicide MCPA, where six carbon atoms are replaced with the carbon-13 isotope. This compound is essential as an internal standard for precise quantitative analysis in environmental and agricultural research, ensuring accurate measurement and traceability. It is primarily needed by analytical laboratories, agrochemical manufacturers, and regulatory bodies involved in mass spectrometry-based methods for residue testing, metabolic studies, and environmental fate analysis.

Application

• Internal Standard for LC/MS and GC/MS: Used for the accurate quantification of MCPA and related phenoxy herbicides in complex matrices.
• Environmental Monitoring: Critical for tracing herbicide residues in soil, water, and plant samples with high precision.
• Metabolic Pathway Studies: Employed in agricultural research to investigate the absorption, distribution, metabolism, and excretion (ADME) of MCPA in crops and ecosystems.
• Quality Control & Method Validation: Serves as a reference standard in analytical method development and validation for agrochemical quality assurance.
• Forensic Analysis: Supports investigations into pesticide misuse or environmental contamination events.
• Regulatory Compliance Testing: Facilitates testing to ensure compliance with maximum residue limits (MRLs) set by global food safety authorities.
