Description

2,2′,3,5,5′‐Pentabromodiphenyl Ether Standard Solution is a certified reference material (CRM) of a specific polybrominated diphenyl ether (PBDE) congener, provided in a ready-to-use solution. This product is essential for instrument calibration, method validation, and quality control in analytical laboratories to ensure accurate and reliable results. It is primarily needed by environmental testing, food safety, and industrial hygiene labs for the precise quantification of this brominated flame retardant congener in various matrices.

Application

• Analytical Reference Standard: For the calibration of GC-MS, GC-ECD, and LC-MS systems in the analysis of brominated flame retardants.
• Method Development & Validation: A critical component for establishing and verifying the accuracy, precision, and detection limits of analytical methods for PBDEs.
• Quality Assurance/Quality Control (QA/QC): Used as a spike for recovery studies and as a system suitability check in routine environmental and product testing.
• Environmental Monitoring: Quantification of 2,2′,3,5,5′‐Pentabromodiphenyl Ether in soil, sediment, water, and air samples to assess contamination levels.
• Food and Feed Safety Analysis: Detection and measurement of this PBDE congener in food products, animal feed, and dietary supplements for regulatory compliance.
• Consumer Product Testing: Analysis of plastics, textiles, and electronics to ensure compliance with regulations like RoHS and REACH concerning restricted substances.
• Toxicological and Biomonitoring Studies: Used in research to study the environmental fate, bioaccumulation, and health effects of specific PBDE congeners.

Quality Control

Every batch of our 2,2′,3,5,5′‐Pentabromodiphenyl Ether Standard Solution is manufactured and certified against traceable primary reference materials. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing detailed information on concentration, solvent, uncertainty, and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to its highly volatile nature, ensure the container is securely sealed and stored upright to prevent leakage or solvent evaporation. Allow the solution to reach room temperature before opening to avoid condensation.
