2-ethylhexyl 2,3,4,5-tetrabromobenzoate

2-Ethylhexyl 2,3,4,5-tetrabromobenzoate (CAS 183658-27-7), also referenced as EH-TBB or TBB, is a brominated aromatic ester used as a non-polymeric flame retardant.

Where is 2-ethylhexyl 2,3,4,5-tetrabromobenzoate used?

• Flexible polyurethane foam: primary component of next-generation flame retardant blends developed as alternatives to legacy brominated compounds, particularly in furniture and bedding
• Textile back-coating: flame resistance in upholstery fabrics and curtains without compromising flexibility
• Plastics processing: compounded into soft PVC and engineering resins where halogenated flame retardancy is required
• Leather and paper treatments: surface-applied flame retardant finishes meeting regulatory or commercial fire standards
• It functions by interrupting combustion in polymer matrices, helping end products meet fire safety standards.

Commercial specifications

• Purity confirmed by bromine content and ester assay
• Bulk and drummed packaging
