Description

Pcb No.101-2,2',4,5,5'-Pentachlorobiphenyl CAS NO 37-60-5 is a specific congener of polychlorinated biphenyls (PCBs), characterized by its five chlorine substituents at the 2, 2', 4, 5, and 5' positions on the biphenyl ring. This compound is of significant importance as a high-purity analytical reference standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily needed by analytical laboratories, environmental agencies, and research institutions engaged in the trace analysis of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration and quantification of PCB congeners in soil, water, sediment, and air samples via GC-MS or GC-ECD.
• Toxicological and Ecotoxicological Research: Serves as a precise standard in studies investigating the bioaccumulation, metabolic pathways, and chronic toxicity of specific PCB congeners.
• Regulatory Compliance and Method Validation: Essential for validating analytical methods to ensure compliance with international regulations such as the Stockholm Convention on POPs, EPA methods, and EU directives.
• Quality Assurance/Quality Control (QA/QC): Employed in laboratory proficiency testing and as an internal standard to ensure the accuracy and precision of PCB congener analysis.
• Forensic and Source Identification Studies: Aids in chemical fingerprinting to identify the sources and weathering patterns of PCB contamination in the environment.
• Manufacturing of Calibration Solutions: Used by manufacturers to prepare precise, multi-component calibration mixes for environmental testing laboratories.

Quality Control

Our PCB 101 reference material is produced and handled under strict quality protocols to ensure the highest standard of purity and traceability required for analytical applications. Each batch is characterized using advanced analytical techniques including high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) and is supplied with a comprehensive Certificate of Analysis (COA). The COA provides detailed information on purity, congener-specific identity confirmation, and potential trace impurities, supporting ISO/IEC 17025 and GMP compliant laboratory operations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is light-sensitive (store away from light) and should be handled with appropriate precautions in a well-ventilated area. For long-term stability, storage under inert atmosphere is recommended.
