Description

2-Chlorobenzoic Acid-[13C6] is a stable isotope-labeled analog of 2-chlorobenzoic acid, where all six carbon atoms are the non-radioactive carbon-13 isotope. This compound is essential as an internal standard for precise quantitative analysis using mass spectrometry, eliminating variability and ensuring data accuracy. It is primarily required by analytical laboratories, pharmaceutical R&D teams, and agrochemical companies engaged in advanced method development, metabolic studies, and environmental fate tracking.

Application

• Internal Standard for LC-MS/GC-MS: Serves as a critical reference compound for the accurate quantification of 2-chlorobenzoic acid and related metabolites in complex biological and environmental matrices.
• Pharmaceutical Research: Used in drug metabolism and pharmacokinetics (DMPK) studies to trace the absorption, distribution, metabolism, and excretion (ADME) of pharmaceutical compounds.
• Environmental Analysis: Enables precise monitoring and quantification of chlorobenzoic acid pollutants or degradation products in water, soil, and industrial waste samples.
• Agrochemical Science: Facilitates the study of herbicide and pesticide degradation pathways and environmental persistence.
• Biochemical Tracing: Employed in metabolic pathway elucidation and proteomics research where carbon flux needs to be tracked.
• Method Development & Validation: A key tool for developing, optimizing, and validating highly sensitive and specific analytical methods in compliance with regulatory guidelines.
