Description

Heptachloro-1,1'-Biphenyl is a specific, high-purity polychlorinated biphenyl (PCB) congener. This compound is critical for analytical and research applications where a defined chemical standard is required for calibration, method development, and environmental testing. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and toxicological studies.

Application

• Analytical Reference Standard: Serves as a certified reference material (CRM) for the quantification of PCBs in environmental samples via GC-MS or GC-ECD.
• Environmental Monitoring: Used in the calibration of equipment for testing soil, water, and air samples to comply with global POPs regulations.
• Method Development & Validation: Essential for developing and validating analytical methods in accredited testing laboratories.
• Toxicological Research: Employed in scientific studies investigating the bioaccumulation, metabolic pathways, and health effects of specific PCB congeners.
• Quality Control & Assurance: Acts as an internal standard or spike in quality control procedures to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: A key component in test kits and procedures for verifying compliance with international standards like the Stockholm Convention.

Quality Control

Every batch of our Heptachloro-1,1'-Biphenyl is produced and analyzed under strict quality management protocols to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing purity, chromatographic data, and confirmatory testing. Our standards are suitable for use in methods requiring traceable and reliable reference materials, supporting compliance with ISO/IEC 17025 and GLP principles.

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 tightly sealed in a dry environment to prevent moisture absorption.
