Description

3,3',4,5-Tetrachlorobiphenyl CAS NO 70362-49-1 is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This high-purity reference standard is critical for analytical research, environmental monitoring, and regulatory compliance testing. It is primarily utilized by analytical laboratories, environmental agencies, and research institutions involved in the detection and quantification of persistent organic pollutants.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating equipment like GC-MS and HPLC in environmental and food testing laboratories.
• Environmental Monitoring: Used in the analysis of soil, sediment, water, and air samples to assess PCB contamination levels and track pollution sources.
• Toxicological Research: Serves as a precise congener for studying the specific biological effects, metabolic pathways, and toxicity profiles of PCBs.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for PCB detection and quantification.
• Quality Control & Assurance: Employed in internal QC/QA programs to ensure the accuracy and reliability of analytical data in commercial testing labs.
• Regulatory Compliance Testing: Used to verify compliance with international regulations (e.g., Stockholm Convention, EPA methods) concerning POPs (Persistent Organic Pollutants).

Quality Control

Every batch of our 3,3',4,5-Tetrachlorobiphenyl is produced and handled under strict quality management protocols. We guarantee high chemical purity and stability, with identity and concentration verified against certified reference materials. A comprehensive Certificate of Analysis (COA) detailing purity, analytical methods (e.g., GC-FID, GC-MS), and traceability is provided with each shipment to ensure data integrity for your critical research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). For long-term stability, storage at 2-8°C is recommended. Keep away from heat and incompatible materials.
