Understanding the fundamental properties of chemical reference materials is essential for their effective application in scientific research and regulatory compliance. Aroclor 1242, a historically significant mixture of polychlorinated biphenyls (PCBs), remains a vital standard in analytical chemistry, particularly for environmental monitoring. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Aroclor 1242, enabling laboratories to perform accurate assessments of environmental contaminants.

Aroclor 1242 is characterized by its specific composition of chlorinated biphenyls, containing approximately 42% chlorine by weight. This precise formulation influences its physical and chemical properties, making it a suitable calibration standard for various analytical techniques. While its industrial use has been phased out due to environmental concerns, its role as a reference standard is more critical than ever. The CAS number for this particular Aroclor mixture is 53469-21-9, a key identifier for procurement and laboratory record-keeping. Understanding the Aroclor 1242 chemical properties, such as its stability and solubility in various solvents, is crucial for analysts.

The primary application of Aroclor 1242 lies in its use as a standard for the detection and quantification of PCBs in environmental samples. It is explicitly mentioned in several EPA methods, including Method 505, 508, 608, and 8082, which are widely employed for monitoring contaminants in water sources, wastewater, and soil. Laboratories use these standards to calibrate their Gas Chromatography (GC) and GC/Mass Spectrometry (MS) systems, ensuring that the instruments can accurately identify and measure the concentrations of PCBs present in samples. This process is fundamental to effective environmental testing and crucial for regulatory compliance.
