Description

3,5-Dichlorobiphenyl CAS NO 34883-41-5 is a specific chlorinated biphenyl derivative, a class of compounds historically significant in industrial chemistry and now primarily used as a critical reference standard and research chemical. Its precise structure makes it an essential tool for analytical method development, environmental monitoring, and toxicological studies related to polychlorinated biphenyls (PCBs). This high-purity compound is vital for researchers and quality control laboratories in the environmental testing, chemical manufacturing, and regulatory compliance sectors who require reliable and well-characterized materials for calibration and verification.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) in environmental and food testing laboratories.
• Environmental Analysis: Calibration and quantification of PCB congeners in soil, water, sediment, and air samples to comply with environmental protection regulations.
• Toxicological Research: Used in scientific studies to investigate the metabolism, persistence, and specific toxic effects of individual PCB congeners.
• Method Development & Validation: Serves as a key component in developing and validating new analytical methods for the detection of halogenated organic compounds.
• Quality Assurance/Quality Control (QA/QC): Employed as an internal standard or spike recovery standard to ensure the accuracy and precision of analytical data in commercial testing labs.
• Chemical Synthesis Intermediate: Can be used as a building block in organic synthesis for creating more complex molecules for research purposes.
