Description

1,2-Dichlorobenzene (CAS 95-50-1), commonly known as ODCB, is a high-boiling aromatic solvent used across industrial processing and chemical manufacturing. It functions as a process solvent, carrier, and intermediate where thermal stability is required. This chemical provides strong solvency for non-polar substrates in various industrial environments. In textile and leather processing, ODCB serves as a carrier solvent for disperse dyes, enabling uniform dye penetration into synthetic fibers.

The coatings and adhesives industry uses it to dissolve resins, pigment dispersions, and elastomer compounds. It is particularly effective where conventional solvents lack sufficient solvency power for specialized industrial applications. In plastics and polymer manufacturing, it acts as a reaction medium and processing solvent. It is used extensively in polyphenylene sulfide (PPS) synthesis and other high-performance polymer production cycles.

Water treatment and industrial biocide formulations also incorporate ODCB as a solvent carrier. It helps deliver active ingredients targeting microbial control in large-scale industrial water systems and cooling towers. 1,2-Dichlorobenzene is supplied as a clear liquid in bulk quantities, including ISO tank, drum, and IBC formats. Technical grade is the standard commercial specification, with purity levels typically at 99% or higher.

Refined grades meeting tighter purity thresholds are available for sensitive synthesis and formulation applications. Our logistics network ensures reliable delivery of high-purity solvents to meet your specific manufacturing requirements.
