Description

3,3′,5,5′‐Tetrabromodiphenyl Ether Standard Solution is a certified reference material (CRM) of a polybrominated diphenyl ether (PBDE) congener, essential for analytical calibration and quality assurance. This high-purity standard solution provides the accuracy and traceability required for precise quantitative analysis in environmental and product safety testing. It is a critical tool for laboratories in the environmental monitoring, electronics, and consumer goods industries to ensure regulatory compliance and assess contamination levels.

Application

• Quantitative Analytical Calibration: Primary use as a certified reference standard for Gas Chromatography (GC) and Liquid Chromatography (LC) methods, including GC-MS and LC-MS/MS.
• Environmental Monitoring: Calibration for the detection and quantification of PBDEs in soil, sediment, water, and air samples to assess pollution.
• Material and Product Safety Testing: Used in the analysis of plastics, textiles, electronics (RoHS compliance), and other consumer products for brominated flame retardant content.
• Food and Feed Safety: Method development and calibration for monitoring PBDE residues in food chains and animal feed.
• Forensic and Research Laboratories: Serves as a definitive standard in academic, governmental, and industrial research on brominated flame retardants.
• Quality Control & Method Validation: Essential for establishing detection limits, precision, and accuracy in laboratory testing protocols.
• Regulatory Compliance: Supports testing for global regulations such as REACH, TSCA, and various international restrictions on persistent organic pollutants (POPs).

Quality Control

Every batch of our 3,3′,5,5′‐Tetrabromodiphenyl Ether Standard Solution is manufactured and certified under strict quality management systems. The concentration and purity are verified using orthogonal analytical techniques including GC-FID, GC-MS, and NMR against traceable primary standards. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the certified concentration, uncertainty, expiration date, and storage conditions to ensure data integrity for your laboratory's accreditation needs (ISO/IEC 17025, GLP).

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 upright to prevent solvent evaporation and concentration change. Allow the solution to equilibrate to room temperature before use and mix thoroughly.
