Description

4,4'-Dde (13C12) is a stable isotope-labeled derivative of the 4,4'-diaminodiphenyl ether (DDE) molecule, where all twelve carbon atoms are the carbon-13 (13C) isotope. This compound is critically important as an internal standard for quantitative mass spectrometry, enabling highly accurate and precise measurements in complex matrices. It is primarily needed by analytical laboratories, pharmaceutical researchers, and environmental testing facilities engaged in advanced trace analysis, method development, and regulatory compliance testing.

Application

• Internal Standard for LC-MS/MS and GC-MS: Used for the accurate quantification of 4,4'-diaminodiphenyl ether and related aromatic amines in environmental, food, and biological samples.
• Pharmaceutical Impurity Profiling: Essential for tracking and quantifying process-related impurities and degradation products in drug substances and products.
• Metabolite Studies: Facilitates the identification and measurement of metabolites in pharmacokinetic and toxicological research.
• Environmental Monitoring: Enables precise analysis of industrial pollutants and chemical residues in water, soil, and air samples.
• Method Development and Validation: Serves as a key component in developing robust, isotope-dilution mass spectrometry (IDMS) analytical methods.
• Quality Control in Chemical Synthesis: Used to monitor reaction yields and purity in the synthesis of polymers and specialty chemicals where DDE is a precursor or intermediate.
