o-Dichlorobenzene

O-Dichlorobenzene (CAS 95-50-1, EC 202-425-9) is an aromatic chlorinated solvent also identified by the abbreviations ODB and o-DCB, and the synonyms Cloroben and NSC 60644. It carries no assigned E-code. Molecular formula C6H4Cl2, it is the ortho isomer of the three dichlorobenzene structural forms.

In coatings and adhesives formulations, o-DCB functions as a high-boiling carrier solvent, dissolving resins and pigment systems that resist lower-polarity alternatives. In textile and leather processing, its antimicrobial activity controls microbial contamination in process baths, while its solvent properties aid dye penetration and fixation. It also serves as a chemical intermediate in flame retardant production for plastics and polymer systems.

O-Dichlorobenzene is supplied in industrial grades compliant with REACH registration requirements. It is available in bulk liquid format and intermediate IBCs. Procurement teams should confirm current SDS documentation and regional authorization status before ordering, as chlorinated aromatic solvents are subject to ongoing regulatory review across EU jurisdictions.
