Description

Polychlorinated Biphenyls (PCBs) are a class of synthetic organic chemicals characterized by their biphenyl structure with varying degrees of chlorination. Historically, their chemical stability, non-flammability, and excellent dielectric properties made them valuable industrial materials. Due to their persistence and bioaccumulative nature, their primary modern relevance is in environmental analysis, reference standard production, and specialized research applications.

Application

• Production of certified reference standards and analytical standards for environmental testing laboratories.
• Use as a critical component in method development and validation for the detection of persistent organic pollutants (POPs).
• Research into environmental fate, toxicology, and remediation technologies for legacy contamination.
• Calibration of analytical instrumentation such as GC-MS and HPLC systems in regulatory and quality control settings.
• Specialized studies in material science investigating historical formulations and their properties.
