Description

2,3,3',5,5',6-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is critical for analytical and research applications where precise chemical identity and purity are paramount. It serves as a vital certified reference material (CRM) and analytical standard for laboratories involved in environmental monitoring, toxicology studies, and regulatory compliance testing.

Application

• Certified Reference Material (CRM) for the calibration of analytical instruments (GC, GC-MS, HPLC).
• Analytical Standard for the quantification and identification of PCB congeners in complex environmental matrices (soil, water, sediment).
• Critical component in toxicological and ecotoxicological research to study the effects of specific PCB congeners.
• Used for method development and validation in analytical laboratories to ensure accuracy and precision.
• Essential for quality assurance/quality control (QA/QC) programs in laboratories performing PCB analysis for regulatory purposes.
• Material for hazard and risk assessment studies related to persistent organic pollutants (POPs).

Quality Control

Every batch of our 2,3,3',5,5',6-Hexachlorobiphenyl is produced and verified to meet the stringent requirements for use as an analytical standard. Our rigorous quality testing includes identity confirmation by multiple spectroscopic methods and purity assessment by high-resolution chromatography. A comprehensive Certificate of Analysis (COA), detailing lot-specific purity, chromatographic data, and storage conditions, is provided with each shipment to ensure traceability and reliability for your critical research and compliance work.

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 -20°C is recommended. Keep the container tightly sealed in a dry environment to prevent any potential moisture absorption.
