Description

2,3,3′,4,5′‐Pentabromodiphenyl Ether Standard Solution is a certified reference material (CRM) of a specific polybrominated diphenyl ether (PBDE) congener, essential for analytical quality control and method validation. This high-purity standard solution provides the critical benchmark required for accurate quantification of PBDEs in complex matrices, ensuring regulatory compliance and data integrity. It is primarily used by analytical laboratories, environmental testing facilities, and research institutions involved in monitoring persistent organic pollutants (POPs) and ensuring product safety.

Application

• Quantitative Analytical Reference Standard for gas chromatography (GC) and liquid chromatography (LC) methods, including GC-MS and LC-MS/MS.
• Calibration and Quality Assurance in environmental testing for PBDEs in soil, water, sediment, and air samples.
• Method Development and Validation for laboratories establishing or verifying analytical procedures for brominated flame retardants.
• Quality Control in Product Safety Testing for electronics, plastics, and textiles to ensure compliance with RoHS, REACH, and other regulatory limits.
• Research and Toxicology Studies investigating the environmental fate, bioaccumulation, and health effects of specific PBDE congeners.
• Proficiency Testing and Laboratory Accreditation (e.g., ISO/IEC 17025) to demonstrate analytical competency.

Quality Control

Every batch of our 2,3,3′,4,5′‐Pentabromodiphenyl Ether Standard Solution is manufactured and certified under strict quality management systems. The solution concentration is precisely quantified using traceable reference standards and validated analytical methods (e.g., GC-FID, GC-MS). Certificates of Analysis (COA) are provided with each unit, detailing the certified concentration, expiration date, measurement uncertainty, and storage conditions. Our quality commitment ensures compliance with standards relevant to reference material producers.

Storage

Preserve in the original tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the solvent, allow the solution to equilibrate to room temperature before opening to prevent condensation. Keep away from strong acids and oxidizing agents. For long-term stability, storage under inert atmosphere is recommended.
