Description

2,3-Dichlorobenzoic-D3 Acid is a deuterium-labeled analog of 2,3-dichlorobenzoic acid, where three hydrogen atoms are replaced with the stable isotope deuterium. This high-purity labeled compound is essential for creating internal standards in quantitative mass spectrometry, ensuring unparalleled accuracy and reliability in analytical measurements. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries for method development, metabolism studies, and trace-level analysis.

Application

• Internal Standard for LC-MS/MS: Serves as a critical, non-interfering reference compound for the precise quantification of 2,3-dichlorobenzoic acid and related metabolites in complex biological matrices.
• Pharmaceutical Research: Used in drug metabolism and pharmacokinetics (DMPK) studies to track the absorption, distribution, metabolism, and excretion of drug candidates containing dichlorobenzoic acid moieties.
• Agrochemical Analysis: Enables accurate residue testing of pesticides or herbicides that degrade to 2,3-dichlorobenzoic acid in soil, water, and crop samples.
• Environmental Monitoring: Facilitates the detection and quantification of chlorinated aromatic pollutants and their degradation products in environmental samples.
• Isotope Dilution Mass Spectrometry (IDMS): A key component in this gold-standard analytical technique for achieving high-accuracy results in certified reference material production.
• Metabolomics and Biomarker Discovery: Assists in the identification and quantification of specific metabolic pathways in biological systems.
