Description

S-(2,3,4-Trihydroxybutyl)Mercapturic Acid is a key mercapturic acid metabolite, serving as a critical biomarker for exposure to specific industrial chemicals and environmental toxins. Its precise quantification is essential for toxicological studies, occupational health monitoring, and advanced biochemical research. This high-purity reference standard is primarily utilized by analytical laboratories, contract research organizations (CROs), and pharmaceutical R&D departments focused on metabolic pathway analysis and safety assessment.

Application

• Biomarker Analysis: Used as a certified reference standard in LC-MS/MS and HPLC methods for the accurate quantification of human exposure to specific alkene oxides and related precursors.
• Toxicology & Metabolomics Research: A vital tool for studying detoxification pathways, specifically the mercapturic acid pathway, in both in vitro and in vivo models.
• Occupational Health & Safety: Enables biological monitoring programs to assess worker exposure in chemical manufacturing and handling environments.
• Pharmaceutical Development: Supports drug metabolism and pharmacokinetics (DMPK) studies by providing a benchmark for related metabolite identification and quantification.
• Environmental Exposure Assessment: Facilitates population-level studies investigating exposure to specific environmental contaminants through biomonitoring.
• Method Development & Validation: Serves as a critical calibrant and quality control material for developing and validating robust analytical assays in clinical and research laboratories.

Quality Control

Every batch of S-(2,3,4-Trihydroxybutyl)Mercapturic Acid is manufactured and analyzed under strict quality management systems. We provide comprehensive analytical data to support its use as a reference standard, including confirmation of identity and high purity by advanced chromatographic and spectroscopic techniques. A detailed Certificate of Analysis (COA) containing batch-specific results for purity, related substances, and residual solvents is supplied with each shipment to ensure traceability and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to prevent moisture uptake and degradation. For long-term storage, consider desiccated conditions.
