Description

2,4,6-Trichlorobiphenyl-2',3',4',5',6'-D5 is a deuterated analog of a polychlorinated biphenyl (PCB) congener, specifically designed for use as an internal standard in analytical chemistry. This high-purity, isotopically labeled compound is critical for ensuring the accuracy and reliability of mass spectrometry-based analyses by correcting for instrument variability and sample preparation losses. It is an essential tool for environmental testing laboratories, regulatory agencies, and research institutions conducting trace-level quantification of PCBs in complex matrices such as soil, water, and biological tissues.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Primary application for the precise quantification of native PCB congeners in environmental and biological samples.
• Environmental Monitoring and Analysis: Used in EPA and other international methods for tracking PCB contamination in air, water, sediment, and soil.
• Food Safety and Regulatory Testing: Enables accurate measurement of PCB residues in food products, feed, and edible oils to ensure compliance with safety limits.
• Toxicological and Biomedical Research: Supports studies on PCB metabolism, bioaccumulation, and health impact assessments by providing a stable isotopic tracer.
• Waste and Remediation Site Analysis: Critical for characterizing PCB profiles in industrial waste and monitoring the effectiveness of remediation efforts.
• Method Development and Validation: Serves as a key component in developing, optimizing, and validating new analytical protocols for halogenated organic compounds.
• Quality Assurance/Quality Control (QA/QC): Integral to laboratory QA/QC programs, ensuring data integrity for certified reporting and regulatory submissions.

Quality Control

Every batch of 2,4,6-Trichlorobiphenyl-2',3',4',5',6'-D5 is manufactured and analyzed under strict quality systems to ensure the high chemical and isotopic purity required for analytical standards. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request and provide batch-specific data for critical parameters including isotopic purity (D-enrichment), chemical purity (by GC-MS), and confirmation of structure.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) upon receipt for long-term stability. For short-term use, the container may be kept at controlled room temperature (15-25°C). Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. Store in a cool, dry, and well-ventilated area dedicated for chemicals.
