Description

3,4,5-Tribromophenol CAS NO 116434-90-3 is a halogenated phenolic compound characterized by its three bromine substituents, offering unique reactivity and properties. This chemical serves as a versatile and critical brominated intermediate in advanced organic synthesis. It is primarily required by manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for the development of active ingredients and flame retardants.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring brominated aromatic structures.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where bromine incorporation enhances biological activity.
• Flame Retardant Precursor: Acts as a starting material for the manufacture of brominated flame retardants (BFRs) used in polymers, textiles, and electronics.
• Organic Synthesis Reagent: Employed in laboratories and industrial settings for bromination reactions, coupling reactions, and as a precursor to more complex molecules.
• Material Science Research: Utilized in R&D for developing novel polymers, liquid crystals, and other advanced materials with specific thermal or electronic properties.
