Description

2,3-Dichlorobenzoic Acid-13C is a stable isotope-labeled analog of 2,3-dichlorobenzoic acid, where the carbon atom at the 1-position is the carbon-13 isotope. This compound is a critical tool for researchers requiring precise internal standards in quantitative mass spectrometry, ensuring accurate and reliable analytical data. It is primarily utilized by analytical chemists and scientists in the pharmaceutical, agrochemical, and environmental testing industries for method development, metabolism studies, and residue analysis.

Application

• Internal Standard for Quantitative Analysis: Serves as a high-purity internal standard in LC-MS and GC-MS for the accurate quantification of its non-labeled counterpart or related metabolites.
• Pharmaceutical Research: Used in drug metabolism and pharmacokinetics (DMPK) studies to track and quantify drug compounds and their degradation pathways.
• Environmental Analysis: Enables precise measurement of chlorinated benzoic acid derivatives, which can be environmental pollutants or pesticide degradation products.
• Agrochemical Development: Applied in the analysis of herbicides and plant growth regulators that are based on or metabolize to chlorinated benzoic acid structures.
• Biochemical Tracing: Facilitates metabolic pathway elucidation in biochemical research due to its isotopic label.
• Method Validation: Essential for developing and validating robust, regulatory-compliant analytical methods in quality control laboratories.
