Description

(4-Chloro-1,2-Phenylene)Dimethanol CAS NO 110706-49-5 is a versatile bifunctional aromatic building block featuring both a chloro substituent and two hydroxymethyl groups on the benzene ring. This unique structure makes it a valuable intermediate for synthesizing complex molecules in advanced pharmaceutical and agrochemical research. It is primarily needed by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and material science industries for constructing ligands, polymers, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key synthon for the preparation of novel drug candidates, particularly in kinase inhibitor and antiviral research.
• Agrochemical Synthesis: Building block for creating advanced herbicides, fungicides, and plant growth regulators.
• Ligand and Chelator Precursor: Used to synthesize sophisticated ligands for catalysis and metal-organic frameworks (MOFs).
• Polymer Chemistry: Monomer for producing specialty polyesters, epoxy resins, and other functional polymers with enhanced properties.
• Cross-coupling Reactions: Serves as a substrate in Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to create complex biaryl structures.
• Material Science Research: Intermediate in the development of organic electronic materials and liquid crystals.
