Description

2,2',3,4,4',6,6'-Heptachlorodiphenyl Ether is a specific, high-purity polychlorinated diphenyl ether (PCDE) congener, a class of compounds structurally related to polychlorinated biphenyls (PCBs). This compound is of significant interest for research and analytical applications, particularly as a reference standard for environmental monitoring and toxicological studies. It serves as a critical material for scientists and quality control laboratories in the environmental, chemical analysis, and regulatory compliance sectors who require precise and reliable analytical standards.

Application

• Environmental Analysis Reference Standard: Used for the calibration of analytical equipment (GC-MS, HPLC) to detect and quantify PCDE contaminants in soil, water, and biological samples.
• Toxicological Research: Employed in laboratory studies to investigate the environmental fate, bioaccumulation potential, and toxicological effects of chlorinated diphenyl ethers.
• Method Development and Validation: Serves as a critical component in developing and validating new analytical methods for persistent organic pollutants (POPs).
• Quality Assurance/Quality Control (QA/QC): Acts as an internal or external standard to ensure the accuracy and precision of analytical data in commercial and regulatory testing laboratories.
• Chemical Synthesis Intermediate: May be utilized as a building block or precursor in specialized organic synthesis for research purposes.
• Regulatory Compliance Testing: Used as a certified reference material to help industries comply with environmental regulations concerning halogenated organic compounds.

Quality Control

Every batch of our 2,2',3,4,4',6,6'-Heptachlorodiphenyl Ether is produced and handled under strict quality management protocols. We provide comprehensive analytical data to ensure identity, purity, and consistency, which is essential for its use as a reference material. A detailed Certificate of Analysis (COA) is supplied with each shipment, typically including results from chromatographic purity assays (GC-FID/GC-MS), spectroscopic identification, and verification of molecular weight.

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). Keep away from strong acids and organic solvents. For long-term storage, consider storing under an inert atmosphere to maximize stability.
