Description

2,4,5-Trichlorobiphenyl CAS NO 15862-07-4 is a specific polychlorinated biphenyl (PCB) congener valued for its role as a critical reference standard and research chemical. Its precise chemical structure is essential for analytical calibration, environmental monitoring, and toxicological studies related to PCB contamination. This compound is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified standard for gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to identify and quantify PCBs in complex matrices.
• Environmental Analysis: Calibration and method development for detecting PCB residues in soil, water, sediment, and air samples to assess contamination levels.
• Food and Feed Safety Testing: Used in laboratories to screen for PCB contamination in agricultural products, seafood, and animal feed to ensure regulatory compliance.
• Toxicological Research: Serves as a pure congener in studies investigating the metabolic pathways, bioaccumulation, and specific health effects of individual PCBs.
• Quality Control and Assurance: Employed by chemical manufacturers and testing labs to verify the purity and identity of PCB mixtures or related compounds.
• Regulatory and Forensic Science: Supports legal and environmental investigations by providing a definitive standard for PCB fingerprinting and source identification.
