Description

2,2',3,4,5,6'-Hexachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest for analytical and research purposes, particularly in environmental monitoring and toxicological studies. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions for use as a reference standard or analytical standard to calibrate equipment, validate methods, and quantify PCBs in various matrices.

Application

• Analytical Reference Standard: Primary use for calibration and quantification in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analysis.
• Environmental Analysis: Used to detect, identify, and measure PCB contamination levels in soil, water, sediment, and air samples for regulatory compliance and site assessment.
• Food and Feed Safety Testing: Employed as a standard in the analysis of PCB residues in food products, animal feed, and edible oils to ensure safety standards.
• Toxicological Research: Serves as a precise chemical entity in studies investigating the metabolism, environmental fate, and health effects of specific PCB congeners.
• Method Development and Validation: Critical for developing, optimizing, and validating new analytical methods for PCB detection and speciation in complex samples.
• Quality Control/Quality Assurance (QC/QA): Used in laboratory QC protocols to ensure the accuracy, precision, and reliability of analytical data for PCBs.

Quality Control

Our high-purity analytical standards are produced and handled under strict quality-controlled conditions. Each batch undergoes rigorous analysis using advanced techniques like GC-FID and GC-MS to confirm identity and purity. A comprehensive Certificate of Analysis (COA) is provided, detailing the exact congener purity, solvent content (if applicable), and analytical results. We ensure traceability and compliance with relevant standards for analytical reagents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry 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 to prevent evaporation of solvent or moisture uptake.
