Description

2,2',4,4',6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This compound is of significant importance for analytical and research purposes, particularly in environmental monitoring, toxicology studies, and as a reference standard for calibration. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and method development.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the quantitative and qualitative analysis of PCB congeners in environmental samples via GC-MS or HPLC.
• Environmental Monitoring: Serves as a critical standard for calibrating equipment to detect and quantify PCBs in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Employed in laboratory studies to investigate the specific biological effects, metabolic pathways, and toxicity profiles of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for PCB detection and separation in complex matrices.
• Quality Control & Assurance: Used in internal quality control procedures within laboratories to ensure the accuracy and precision of ongoing PCB analysis.
• Regulatory Compliance Testing: Provides a benchmark for testing products and materials to ensure they comply with international regulations restricting PCB content, such as the Stockholm Convention.

Quality Control

Our high-purity 2,2',4,4',6-Pentachlorobiphenyl is produced and handled under strict quality management protocols. Each batch is rigorously analyzed using advanced chromatographic and spectroscopic techniques to ensure identity, purity, and stability. A comprehensive Certificate of Analysis (COA) is provided, detailing purity (typically ≥98% by GC), chromatographic profile, and other critical parameters. Our quality system is designed to meet the exacting requirements of analytical reference material users.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep away from strong acids and organic solvents. For long-term stability, consider storage under inert atmosphere at lower temperatures (e.g., 2-8°C).
