Description

3,4,5-Trichlorodiphenyl-2',3',4',5',6'-D5 is a deuterated aromatic compound, specifically a pentadeuterated derivative of a trichlorinated biphenyl. This compound is a high-value specialty chemical that serves as a critical stable isotope-labeled internal standard for analytical chemistry. It is essential for researchers and quality control laboratories requiring precise quantification and method validation in complex matrices. Industries involved in environmental analysis, food safety testing, and advanced material research rely on such labeled standards for accurate trace-level detection.

Application

• Internal Standard for Mass Spectrometry (GC-MS, LC-MS): Used for the accurate quantification of polychlorinated biphenyls (PCBs) and related chlorinated aromatic compounds in environmental samples.
• Environmental Monitoring: Critical in testing for PCB contamination in soil, water, sediment, and air to comply with global environmental regulations (e.g., EPA methods).
• Food and Feed Safety Analysis: Employed in laboratories to detect and quantify persistent organic pollutants (POPs) in the food chain.
• Metabolite and Degradation Pathway Studies: Acts as a tracer in research studying the biological or environmental breakdown pathways of chlorinated aromatics.
• Pharmaceutical Impurity Profiling: Can be used as a reference standard in the analysis of chlorinated organic impurities in active pharmaceutical ingredients (APIs).
• Quality Assurance/Quality Control (QA/QC): Serves as a benchmark in laboratory proficiency testing and for calibrating analytical instrumentation.
• Forensic and Doping Control Analysis: Provides a reliable reference point in complex forensic toxicology or anti-doping screens where specificity is paramount.

Quality Control

Every batch of our 3,4,5-Trichlorodiphenyl-2',3',4',5',6'-D5 is produced and analyzed under strict quality management systems. We guarantee high chemical and isotopic purity to meet the exacting demands of analytical reference standards. Comprehensive testing includes NMR (1H, 13C) for structural confirmation and isotopic enrichment, and chromatographic methods (GC, HPLC) for chemical purity assessment. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting the batch-specific results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, consider storage under inert atmosphere (e.g., argon or nitrogen) in a freezer (-20°C). Keep the container tightly sealed to prevent moisture absorption and potential contamination.
