Description

3-Hydroxy-2,5,2',5'-Tetrachlorobiphenyl is a specific hydroxylated derivative of polychlorinated biphenyl (PCB), a compound class of significant industrial and research interest. This chlorinated phenolic compound serves as a crucial high-purity reference standard and synthetic intermediate for advanced chemical synthesis. It is primarily required by research laboratories, analytical service providers, and specialty chemical manufacturers engaged in environmental analysis, toxicology studies, and the development of novel chemical entities.

Application

• Analytical Reference Standard: Used as a certified standard for the calibration and quantification of hydroxylated PCB metabolites in environmental and biological samples via GC-MS or LC-MS.
• Environmental Research: Critical for studying the environmental fate, biodegradation pathways, and metabolic profiles of polychlorinated biphenyls (PCBs).
• Toxicological Studies: Employed in research to investigate the biochemical interactions, toxicity mechanisms, and endocrine-disrupting potential of PCB derivatives.
• Chemical Synthesis: Acts as a key synthetic building block or precursor for the preparation of more complex halogenated aromatic compounds and specialized materials.
• Method Development: Utilized by analytical chemists to develop and validate new chromatographic or spectroscopic methods for detecting trace organic pollutants.
• Quality Control: Serves as an internal standard or spike in quality assurance/quality control (QA/QC) protocols for laboratories analyzing persistent organic pollutants (POPs).

Quality Control

Our 3-Hydroxy-2,5,2',5'-Tetrachlorobiphenyl is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity, suitable for research and analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles. We ensure compliance with relevant standards for high-purity reference materials. Certificates of Analysis (COA) are available upon request.

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, sparks, and open flame. Due to its light-sensitive nature, the container should be amber-colored or stored in dark conditions.
