Description

4,4'-Ddt (13C12) is a stable isotope-labeled analog of the classic organochlorine pesticide, DDT, where all 12 carbon atoms are replaced with the Carbon-13 isotope. This compound is essential for use as an internal standard in high-precision analytical methods, providing unmatched accuracy for quantification and traceability. It is a critical material for environmental testing laboratories, regulatory agencies, and research institutions conducting residue analysis, method development, and environmental fate studies. The product is supplied with full analytical documentation to ensure data integrity and regulatory compliance.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Primary use as a quantitative reference standard in isotope dilution mass spectrometry for accurate pesticide residue analysis.
• Environmental Monitoring and Analysis: Calibration and quality control in the testing of soil, water, and air samples for persistent organic pollutant (POP) contamination.
• Food Safety and Agricultural Testing: Ensuring accurate detection and quantification of DDT and its metabolites in food products, crops, and animal feed to comply with maximum residue limits (MRLs).
• Method Development and Validation: Used by analytical chemists to develop, optimize, and validate new testing protocols for organochlorine compounds.
• Forensic and Regulatory Science: Supporting investigations and compliance checks by providing a traceable standard for definitive identification and measurement.
• Metabolite and Degradation Studies: Research tool for tracking the environmental breakdown pathways and metabolic products of DDT.
