Description

Aroclor 1016, 1X5Ml, Transformer Oil 50M G/Kg CAS NO 12674-11-2 is a specific, low-chlorine formulation of polychlorinated biphenyl (PCB) historically used as a dielectric fluid and heat transfer agent. Its primary commercial value lies in its chemical stability and electrical insulating properties, which were critical for high-performance industrial applications. This product is essential for analytical laboratories, environmental testing facilities, and industrial maintenance teams requiring a reference standard for the identification, quantification, and remediation monitoring of PCBs in legacy electrical equipment and contaminated sites.

Application

• Primary use as a reference standard and calibrant for gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analysis in environmental testing.
• Critical component in quality control and method development for laboratories analyzing PCB contamination in soil, water, and waste oils.
• Used for performance verification and calibration of analytical instruments dedicated to monitoring transformer and capacitor fluids.
• Essential material for research and development of PCB degradation, remediation, and disposal technologies.
• Employed in forensic analysis to fingerprint and trace the source of PCB contamination in industrial accidents or legacy sites.
• Used for training and proficiency testing programs for analytical chemists and environmental scientists.

Quality Control

This analytical standard is produced and verified under strict quality protocols to ensure identity, purity, and consistency for reliable quantitative analysis. Each batch is characterized using advanced chromatographic techniques against certified reference materials. A comprehensive Certificate of Analysis (COA) is provided, detailing the congener profile, assay, and chromatographic purity. Our quality system is designed to support compliance with environmental monitoring standards such as EPA Methods.

Storage

Preserve in the original tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong bases and organic solvents. For prolonged stability, storage at 2-8°C is recommended. Due to the persistent and bioaccumulative nature of PCBs, follow all local, national, and international regulations (e.g., Stockholm Convention, TSCA) for handling and disposal.
