Description

2,3′,5,5′‐Tetrabromodiphenyl Ether Standard Solution is a high-purity, certified reference material (CRM) used for analytical calibration and quality control. This solution is critical for ensuring the accuracy and reliability of instrumental analyses, particularly in environmental and regulatory testing. It is an essential tool for analytical laboratories, quality assurance departments, and research institutions requiring precise quantification of brominated flame retardants and related compounds.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS) systems.
• Environmental Analysis: Quantification and monitoring of polybrominated diphenyl ethers (PBDEs) in soil, water, and air samples for environmental compliance and research.
• Food Safety Testing: Used in methods to detect and measure brominated flame retardant residues in food products and packaging materials.
• Material Safety Compliance: Assisting in the analysis of consumer products (e.g., plastics, textiles, electronics) for restricted substances under regulations like RoHS and REACH.
• Method Development & Validation: Serving as a key component in developing, optimizing, and validating new analytical methods for brominated compounds.
• Quality Control (QC) & Proficiency Testing: Acting as a benchmark in laboratory QC protocols and inter-laboratory comparison studies to ensure data integrity.
• Toxicological & Metabolic Studies: Providing a known quantity of the analyte for research into the environmental fate, bioaccumulation, and toxicity of PBDE congeners.

Quality Control

Every batch of our 2,3′,5,5′‐Tetrabromodiphenyl Ether Standard Solution is manufactured and certified under strict quality management systems. The solution is characterized using orthogonal analytical techniques including GC-MS and HPLC to confirm identity, purity, and concentration. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the certified value, measurement uncertainty, traceability to national standards, and expiration date. Our quality protocols are designed to meet the needs of ISO/IEC 17025 accredited laboratories and regulatory compliance frameworks.

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 when not in use and allow it to equilibrate to room temperature before opening to prevent condensation. Keep away from heat and open flame.
