Description

3,3'-[1-Methylethylidenebis(2,6-Dibromo-4,1-Phenyleneoxy)]Bis(1-Chloro-2-Propanol) CAS NO 101622-05-3 is a halogenated, multi-functional organic compound characterized by its brominated aromatic and chlorinated propanol groups. This molecular structure makes it a valuable reactive intermediate and flame retardant synergist in advanced material synthesis. It is primarily sought by manufacturers in the polymer, flame retardant, and specialty chemical industries for creating high-performance additives and cross-linked networks.

Application

• Flame Retardant Intermediate: Serves as a key building block for synthesizing novel brominated and phosphorus-bromine synergistic flame retardants for engineering plastics and thermosets.
• Polymer Modification: Used as a reactive monomer or cross-linking agent to introduce flame-retardant properties directly into polymer backbones, such as in epoxy resins, polyurethanes, and polyesters.
• Additive Synthesis: A precursor for manufacturing specialized additives that enhance the fire resistance of textiles, coatings, and wire & cable insulation.
• Research & Development: Employed in laboratories for developing new halogenated compounds with specific thermal and chemical properties.
• Specialty Chemical Production: Functions as an intermediate in the multi-step synthesis of complex molecules for agrochemicals or pharmaceuticals.
