Description

2-Hydroxy-2',3',4',5,5'-Pentachlorobiphenyl is a specific polychlorinated biphenyl (PCB) derivative, distinguished by the presence of a hydroxyl group on the biphenyl core. This compound is of significant interest in research and analytical chemistry, particularly for use as a reference standard or analytical standard in environmental and toxicological studies. It is primarily utilized by professionals in environmental testing laboratories, regulatory agencies, and academic research institutions for the calibration of equipment and the accurate quantification of PCB metabolites in complex matrices.

Application

• Analytical Reference Standard: Primary use for calibrating analytical instruments like GC-MS or HPLC in environmental analysis.
• Environmental Monitoring: Used in method development and validation for detecting and quantifying hydroxylated PCB metabolites in soil, water, and biological samples.
• Toxicological Research: Serves as a precise chemical standard in studies investigating the metabolism, distribution, and health effects of PCBs.
• Quality Control: Employed as an internal or external standard in laboratory QC protocols to ensure accuracy and reproducibility of test results.
• Regulatory Compliance Testing: Essential for laboratories performing tests to comply with environmental regulations concerning persistent organic pollutants (POPs).
• Method Development: A critical tool for scientists developing new analytical techniques for the separation and identification of complex PCB mixtures and their derivatives.
