Description

2,2',3,4',5,6'-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant importance for research, analytical, and regulatory purposes, serving as a critical reference standard and a model compound in environmental fate and toxicology studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, method development, and compliance monitoring.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration and validation of analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Fate and Toxicology Research: Used in scientific studies to understand the behavior, degradation, and toxicological profile of specific PCB congeners in ecosystems.
• Method Development and Validation: Essential for developing, optimizing, and verifying analytical methods for the detection and quantification of PCBs in complex matrices (e.g., soil, water, biota).
• Quality Control and Assurance: Employed in laboratory QC protocols to ensure the accuracy and precision of PCB analysis for regulatory compliance.
• Regulatory Compliance Testing: Used as a standard in testing to comply with international regulations concerning POPs, such as the Stockholm Convention.
• Educational and Training Purposes: Serves as a teaching tool in academic and professional settings for chromatography and mass spectrometry training.

Quality Control

Our high-purity 2,2',3,4',5,6'-Hexachlorobiphenyl is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis (GC-FID/GC-MS) and identity confirmation (NMR/IR), to ensure it meets exacting standards for use as a reference material. Certificates of Analysis (COA) with detailed chromatograms and spectroscopic data are provided to guarantee traceability, purity, and consistency for your critical research and compliance needs.

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). For long-term stability, storage at 2-8°C is recommended. Keep the container tightly sealed under an inert atmosphere to prevent degradation.
