Description

2-Chloropyridine-13C5 is a stable isotope-labeled derivative of 2-chloropyridine, where all five carbon atoms are the carbon-13 isotope. This compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing in complex matrices. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require high-fidelity isotopic labeling for mass spectrometry (MS) and nuclear magnetic resonance (NMR) studies.

Application

• Internal Standard for Quantitative Analysis: Serves as a critical reference standard in LC-MS and GC-MS methods for the accurate quantification of 2-chloropyridine and its metabolites in biological and environmental samples.
• Metabolic Pathway Research: Used in pharmacokinetic and drug metabolism studies to trace the biotransformation and distribution of pyridine-based compounds.
• Pharmaceutical Intermediate Synthesis: Acts as a labeled building block in the synthesis of deuterated or 13C-labeled active pharmaceutical ingredients (APIs) for clinical research.
• Environmental Fate Studies: Employed to study the degradation, absorption, and translocation of chloropyridine herbicides and pollutants.
• NMR Spectroscopy: Provides a non-radioactive tracer for structural elucidation and reaction mechanism studies due to its distinct 13C NMR signature.
• Quality Control & Method Development: Essential for developing and validating robust analytical methods in regulatory and quality control laboratories.
