Description

Octachlorobiphenylene is a highly chlorinated biphenyl derivative, structurally related to polychlorinated biphenyls (PCBs), and is identified by CAS No. 7090-45-1. This compound serves as a critical reference standard and analytical intermediate for environmental monitoring and toxicological research. It is primarily needed by research institutions, analytical laboratories, and chemical manufacturers involved in studying persistent organic pollutants (POPs), developing detection methods, and synthesizing specialized halogenated compounds.

Application

• Environmental Analytical Reference Standard: Used for the calibration of GC-MS and HPLC systems in the detection and quantification of chlorinated aromatic pollutants in soil, water, and biological samples.
• Toxicology and Ecotoxicology Research: Serves as a model compound for studying the environmental fate, bioaccumulation, and toxic effects of highly chlorinated organic molecules.
• Chemical Synthesis Intermediate: Acts as a precursor or building block in organic synthesis for creating more complex halogenated aromatic structures for specialized applications.
• Method Development and Validation: Employed by testing laboratories to develop, optimize, and validate analytical methods for compliance with environmental regulations concerning POPs.
• Quality Control Material: Used as a known compound in laboratory proficiency testing and inter-laboratory comparison studies to ensure analytical accuracy.
• Regulatory and Forensic Science: Supports investigations and regulatory compliance efforts related to the identification of PCB-like compounds in environmental forensic cases.

Quality Control

Our Octachlorobiphenylene is produced and handled under strict quality protocols to ensure high purity and batch-to-batch consistency, suitable for analytical and research applications. Each batch undergoes rigorous testing, including identity confirmation by spectroscopic methods and purity assessment by chromatography. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory documentation needs.

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). Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging. Keep away from heat and incompatible materials.
