Description

2',3,3',4,5-Pentachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant value as a certified reference material and analytical standard for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection, quantification, and study of persistent organic pollutants (POPs) in compliance with global environmental regulations.

Application

• Certified Reference Standard (CRM) for the calibration of analytical instruments (GC, GC-MS, HPLC).
• Analytical Method Development and Validation for the precise detection of PCB congeners in complex matrices.
• Environmental Analysis of soil, sediment, water, and air samples to assess contamination levels.
• Food and Feed Safety Testing to monitor and ensure compliance with maximum residue limits (MRLs).
• Toxicological and Ecotoxicological Research to study the fate, transport, and biological effects of specific PCB congeners.
• Quality Control/Quality Assurance (QC/QA) in laboratories performing routine PCB analysis.

Quality Control

Our high-purity 2',3,3',4,5-Pentachlorobiphenyl is produced and handled under strict quality management protocols. Each batch is characterized using advanced analytical techniques including GC-FID/GC-MS and HPLC to ensure identity, purity, and congener specificity. A comprehensive Certificate of Analysis (COA) is provided, detailing batch-specific results. We support compliance with standards relevant to reference materials and environmental monitoring.

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 and sources of ignition. For long-term stability, storage under inert atmosphere (e.g., argon) in amber glass vials is recommended.
