Description

2,2',3,4,4',6-Hexabde (Bde-139) is a specific brominated diphenyl ether congener, a class of compounds historically used as flame retardants. This high-purity reference standard is critical for analytical research, environmental monitoring, and regulatory compliance testing. It is primarily required by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in research and development or quality control for persistent organic pollutants.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments like GC-MS and HPLC in environmental and food testing laboratories.
• Environmental Monitoring: Used in the analysis of soil, water, sediment, and air samples to detect and quantify levels of brominated flame retardants for pollution studies.
• Toxicological Research: Serves as a precise material for studying the environmental fate, bioaccumulation, and potential health effects of specific PBDE congeners.
• Product Safety & Compliance Testing: Essential for testing consumer products, electronics, and textiles to ensure compliance with international regulations restricting the use of certain brominated flame retardants (e.g., RoHS, REACH).
• Method Development: A key component in developing and optimizing new analytical methods for the separation and detection of complex PBDE mixtures.
• Quality Control: Used by chemical suppliers to verify the identity and purity of related brominated flame retardant products or mixtures.

Quality Control

Every batch of 2,2',3,4,4',6-Hexabde (Bde-139) is produced and analyzed to meet the stringent requirements for an analytical reference material. Our quality assurance includes rigorous identity confirmation and purity assessment using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing batch-specific purity, chromatographic data, and storage conditions is provided with each shipment to ensure traceability and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). For long-term stability, storage at 2-8°C is recommended. Keep the container tightly sealed in a dry environment to prevent moisture absorption.
