Description

2,2',3,3',4,6-Hexachlorobiphenyl CAS NO 61798-70-7 is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This high-purity reference standard is critical for analytical and research applications, enabling precise identification, quantification, and study of PCB compounds. It is primarily utilized by environmental testing laboratories, regulatory agencies, and research institutions focused on contamination analysis, toxicology studies, and method development.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments (GC-MS, HPLC) in the testing of soil, water, and sediment samples for PCB contamination.
• Food and Feed Safety Testing: Serves as a critical standard in laboratories monitoring and enforcing regulatory limits for PCBs in the food chain, including dairy, meat, and fish products.
• Toxicological and Biomedical Research: Employed in studies investigating the metabolism, environmental fate, and health effects of specific PCB congeners.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical methods to ensure accuracy, precision, and regulatory compliance in PCB detection.
• Quality Control and Proficiency Testing: Used by testing laboratories as an internal quality control standard or in inter-laboratory comparison programs to ensure consistent and reliable analytical results.
• Waste and Industrial Material Analysis: Applied in the characterization of PCB content in transformer oils, capacitors, and other industrial wastes for proper disposal and regulatory reporting.

Quality Control

Our 2,2',3,3',4,6-Hexachlorobiphenyl is produced and handled under strict quality protocols to ensure the integrity required for reference standard applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and chromatographic profile. We adhere to relevant guidelines for reference materials to support reliable and reproducible analytical results in compliance-focused environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). For long-term stability, storage at 2-8°C is recommended. Keep the container sealed to prevent moisture absorption and potential contamination.
