Description

2,2',3,4',4-Pentabde CAS NO 182346-21-0 is a specific, high-purity brominated diphenyl ether congener. This compound is critical for research and development, particularly in environmental analysis and material science, where precise chemical standards are required. It serves as an essential reference standard for laboratories analyzing persistent organic pollutants, flame retardant degradation products, and for quality control in related chemical manufacturing.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical equipment like GC-MS and HPLC in environmental testing laboratories.
• Environmental Research: Used in studies monitoring the fate, transport, and bioaccumulation of brominated flame retardants (BFRs) in ecosystems.
• Toxicological Studies: Serves as a precise material for investigating the health and environmental impact of specific PBDE congeners.
• Quality Control: Employed by chemical producers to verify the composition and purity of flame retardant mixtures or related substances.
• Regulatory Compliance Testing: Essential for laboratories performing analysis to comply with global regulations restricting the use of certain PBDEs (e.g., RoHS, REACH, Stockholm Convention).
• Method Development: A key component in developing and optimizing new analytical methods for the separation and detection of brominated compounds.
