Description

S-(2-Bromophenyl)Mercapturic Acid is a specialized organic compound belonging to the class of mercapturic acids, which are key metabolites in the detoxification pathways of xenobiotics. This high-purity reference standard is critical for analytical research and method development in toxicology and environmental monitoring. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and forensic science industries for the precise detection and quantification of exposure biomarkers.

Application

• Biomarker Reference Standard: Used as a certified reference material (CRM) in analytical methods for detecting human or animal exposure to brominated aromatic compounds.
• Toxicology Research: Essential for studying metabolic pathways, specifically the glutathione conjugation (Phase II metabolism) of 2-bromophenyl derivatives.
• Environmental Monitoring: Employed in the development and validation of LC-MS/MS or HPLC methods to assay mercapturic acid metabolites in biological samples (e.g., urine) for occupational health studies.
• Pharmaceutical Impurity Profiling: Serves as a critical standard in impurity identification and control strategies for APIs synthesized using bromophenyl intermediates.
• Forensic Analysis: Aids in the definitive identification of specific toxicant exposure in forensic toxicology investigations.
• Method Development & Validation: Provides a high-purity benchmark for calibrating instruments and ensuring the accuracy and reproducibility of analytical protocols.
