Description

4-Hydroxy-2',3,3',4',5'-Pentachlorobiphenyl is a specific polychlorinated biphenyl (PCB) derivative, characterized by its hydroxyl and pentachloro substitution pattern. This compound is of significant interest in environmental analysis and toxicological research as a model compound or reference standard for studying the fate, behavior, and metabolic pathways of hydroxylated PCBs. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers engaged in environmental monitoring, method development, and advanced material synthesis.

Application

• Environmental Analytical Reference Standard: Used for the calibration of analytical equipment (GC-MS, HPLC) and as a qualitative/quantitative standard in the analysis of PCB metabolites in environmental samples (water, soil, sediment).
• Toxicology and Metabolite Research: Serves as a key compound in studies investigating the biochemical transformation, toxicity, and endocrine-disrupting potential of hydroxylated PCBs.
• Method Development and Validation: Employed by testing laboratories to develop, optimize, and validate new analytical methods for detecting trace levels of chlorinated organic pollutants and their derivatives.
• Chemical Synthesis Intermediate: Acts as a specialized building block or precursor in organic synthesis for creating more complex chemical architectures in research settings.
• Regulatory Compliance Testing: Used in testing protocols to ensure compliance with environmental regulations concerning persistent organic pollutants (POPs).
• Academic and Industrial Research: Fundamental research tool in universities and corporate R&D departments studying environmental chemistry, pollutant degradation, and ecotoxicology.
