Description

2,3,3',4-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical analytical reference standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is essential for laboratories and research institutions focused on persistent organic pollutant (POP) analysis, environmental forensics, and the development of remediation strategies.

Application

• Environmental Analysis Reference Standard: Used for the calibration and quantification of PCB congeners in environmental samples (soil, water, sediment, air) via GC-MS or GC-ECD.
• Toxicological and Biomedical Research: Serves as a precise standard in studies investigating the metabolism, distribution, and toxic effects (e.g., endocrine disruption, carcinogenicity) of specific PCB congeners.
• Food and Feed Safety Testing: Employed as a calibration standard in the analysis of PCB residues to ensure compliance with international food safety regulations (e.g., EU, FDA).
• Waste and Remediation Monitoring: Acts as a key marker in assessing PCB contamination levels at industrial sites and evaluating the effectiveness of remediation technologies.
• Quality Control and Method Development: Essential for validating analytical methods, conducting laboratory proficiency testing, and ensuring data accuracy in commercial and regulatory labs.
• Regulatory Compliance and Certification: Used by testing facilities to demonstrate compliance with global regulations concerning POPs, such as the Stockholm Convention.

Quality Control

Every batch of our 2,3,3',4-Tetrachlorobiphenyl is produced and handled under strict quality management protocols to ensure identity, purity, and stability. We provide comprehensive Certificates of Analysis (COA) that detail purity (typically ≥98% by GC), confirm identity via spectroscopic methods, and report levels of any related congeners or impurities. Our quality systems support traceability and data integrity for GLP/GMP-compliant research and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, consider storage at 2-8°C. Keep the container tightly sealed in a dry environment to prevent any potential degradation.
