Description

3,3',4,4',5-Pentabb (Pbb-126) is a high-purity brominated biphenyl compound, a member of the polybrominated biphenyl (PBB) family. It serves as a critical reference standard and analytical intermediate for research and quality control in environmental and material science. This compound is essential for laboratories and industries requiring precise calibration for the detection and quantification of brominated flame retardants and related contaminants.

Application

• Analytical Reference Standard: Primary use for calibrating instruments (GC-MS, HPLC) in environmental and food safety testing.
• Environmental Monitoring: Critical for analyzing soil, water, and air samples for PBB contamination levels.
• Toxicological Research: Used in studies investigating the environmental fate, bioaccumulation, and health effects of brominated compounds.
• Quality Assurance/Control: Serves as a benchmark for verifying the purity and identity of related chemical products and materials.
• Method Development: Essential for developing and validating new analytical protocols for persistent organic pollutants (POPs).
• Regulatory Compliance Testing: Supports testing to ensure compliance with international regulations on restricted substances (e.g., RoHS, REACH).
