Description

2,5-Dichlorobiphenyl-D5 is a deuterated internal standard critical for high-precision analytical quantification. This stable isotope-labeled compound is essential for ensuring accuracy and reliability in trace-level detection methods. It is primarily required by analytical laboratories and research institutions conducting environmental monitoring, food safety testing, and advanced material science research where precise measurement of polychlorinated biphenyl (PCB) congeners is necessary.

Application

• Internal Standard for GC-MS and LC-MS analysis of PCBs in environmental samples (soil, water, sediment).
• Quantitative reference material for food safety testing to detect PCB contamination.
• Calibration standard in the analysis of transformer oils and other industrial fluids for dielectric breakdown products.
• Critical component in method development and validation for regulatory compliance testing (e.g., EPA methods).
• Tracer compound in environmental fate and metabolism studies of halogenated aromatics.
• Research tool in the synthesis and characterization of deuterated chemical libraries.
• Quality control standard for laboratories performing proficiency testing and inter-laboratory comparisons.

Quality Control

Our 2,5-Dichlorobiphenyl-D5 is manufactured under strict quality systems to ensure the high isotopic purity and chemical integrity required for analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment, chemical purity, and absence of interfering congeners. We support compliance with standards relevant to environmental and food testing laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry, well-ventilated area. Keep the container tightly sealed to prevent moisture absorption and potential contamination.
