Description

2,2',4-Trichlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical analytical standard and reference material for environmental monitoring, toxicological research, and regulatory compliance testing. It serves essential roles in laboratories and industries focused on persistent organic pollutant (POP) analysis, method development, and quality control. Researchers and quality assurance professionals in environmental testing, chemical manufacturing, and academic institutions rely on high-purity PCB congeners for accurate calibration and data integrity.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS, GC-ECD, and HPLC systems in the analysis of PCBs in soil, water, sediment, and biota.
• Toxicological and Metabolic Studies: Serves as a pure congener standard in research investigating the toxicity, environmental fate, bioaccumulation, and metabolic pathways of specific PCB isomers.
• Method Development and Validation: Essential for developing, optimizing, and validating analytical methods according to protocols from EPA, ISO, and other regulatory bodies.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing, internal standard preparation, and as a spike for recovery studies to ensure analytical accuracy and precision.
• Regulatory Compliance Testing: Used by commercial and government laboratories to test products and environmental samples for compliance with global regulations on POPs (e.g., Stockholm Convention).
• Chemical Synthesis Intermediate: Can be used as a building block or starting material in specialized organic synthesis for research purposes.

Quality Control

Our 2,2',4-Trichlorobiphenyl is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for reference materials. Certificates of Analysis (COA) detailing batch-specific purity, analytical methods (e.g., GC-FID, GC-MS), and traceability are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. For long-term stability, storage under inert atmosphere is recommended.
