Description

Pcb 101-13C12 CAS NO 104130-39-4 is a stable isotope-labeled analog of PCB congener 101, where 12 carbon atoms are replaced with the carbon-13 isotope. This compound is essential for high-precision analytical work, serving as a critical internal standard for the accurate quantification and confirmation of polychlorinated biphenyls in complex matrices. It is primarily needed by environmental testing laboratories, regulatory agencies, and research institutions engaged in trace-level analysis of persistent organic pollutants to ensure data reliability and meet stringent compliance standards.

Application

• Internal Standard for GC-MS/MS Analysis: Used for the precise quantification of native PCB 101 and other congeners in environmental samples via isotope dilution mass spectrometry.
• Environmental Monitoring: Critical for testing soil, sediment, water, and air samples to assess contamination levels and compliance with environmental regulations (e.g., EPA methods).
• Food and Feed Safety Analysis: Employed in the detection and quantification of PCB residues in food products, animal feed, and edible oils to ensure consumer safety.
• Waste and Remediation Studies: Used to analyze PCB levels in industrial waste, landfill leachates, and materials from remediation sites.
• Clinical and Biological Research: Facilitates the study of PCB bioaccumulation, metabolism, and toxicokinetics in biological tissues and fluids.
• Method Development and Validation: Serves as a key component in developing, optimizing, and validating new analytical methods for PCB detection.
• Quality Assurance/Quality Control (QA/QC): Integral to laboratory QA/QC protocols, including recovery studies and the preparation of certified reference materials.

Quality Control

Every batch of Pcb 101-13C12 is manufactured and analyzed under strict quality systems to ensure the highest isotopic and chemical purity required for trace analysis. Our products undergo rigorous quality testing, including comprehensive spectroscopic and chromatographic analysis, to ensure compliance with industry standards for certified reference materials. Certificates of Analysis (COA) are provided with each shipment, detailing isotopic enrichment, chemical purity, and concentration data.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. Due to its highly volatile nature, allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation and loss. Keep the container in a well-ventilated area and away from sources of ignition.
