Description

2,3,3',5,5'-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized in research and analytical chemistry as a critical reference standard for environmental monitoring and toxicological studies. It is essential for laboratories and institutions involved in the analysis of persistent organic pollutants (POPs), regulatory compliance testing, and the development of remediation technologies.

Application

• Environmental Analysis Reference Standard: Used as an analytical standard for the calibration of equipment and quantification of PCB congeners in soil, water, and biological samples.
• Toxicological Research: Serves as a precise congener for studying the specific biological effects, metabolic pathways, and environmental fate of PCBs.
• Regulatory Compliance Testing: Essential for laboratories performing tests to comply with global regulations (e.g., Stockholm Convention, EPA methods) regarding POPs.
• Quality Control Material: Employed in the manufacturing and verification of certified reference materials (CRMs) for environmental and food safety testing.
• Method Development and Validation: Critical for developing and validating new analytical methods in gas chromatography (GC) and mass spectrometry (MS).
• Forensic and Source Identification Studies: Aids in chemical fingerprinting to identify the sources and histories of PCB contamination in environmental forensics.

Quality Control

Our high-purity reference standards are produced under strict quality management protocols. Each batch is characterized using advanced analytical techniques including GC-MS and HPLC to ensure identity, purity, and stability. A comprehensive Certificate of Analysis (COA) is supplied with each product, detailing lot-specific data. We support compliance with ISO 17034 and ISO/IEC 17025 requirements for reference material producers and testing laboratories.

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 -20°C is recommended. Keep the container in a well-ventilated area and handle according to laboratory safety protocols for chlorinated compounds.
