The Ortho-dichlorobenzene (ODCB) market is a niche but significant segment within the global chemical industry. ODCB is a colorless to yellow liquid with a characteristic pungent odor, and it is primarily used as a versatile solvent and a chemical intermediate in the synthesis of a variety of other chemicals. The market for ODCB is characterized by its reliance on a few key end-use industries and is currently navigating a complex landscape shaped by evolving industrial demands, increasing environmental regulations, and a growing focus on workplace safety.

One of the primary historical and ongoing applications for Ortho-dichlorobenzene is as a high-boiling point solvent. Its ability to dissolve a wide range of organic compounds has made it useful in a variety of industrial processes, such as the degreasing of metals, the cleaning of engines, and the removal of paint and carbon. It has also been used as a solvent in the production of certain pesticides and herbicides.

However, the use of ODCB as a solvent has been declining in many regions due to its environmental and health concerns. ODCB is classified as a hazardous air pollutant and a potential human carcinogen. It is also toxic to aquatic life. This has led to increasingly stringent regulations on its use and emissions, and a push towards the adoption of safer and more environmentally friendly solvents.

As a result, the focus of the Ortho-dichlorobenzene market has been shifting more towards its use as a chemical intermediate. ODCB is a key raw material in the synthesis of 3,4-dichloroaniline, which is an important intermediate in the production of several herbicides, such as diuron and propanil. This application remains a significant driver of the ODCB market, particularly in regions with a large agricultural sector.

ODCB is also used as an intermediate in the production of other chemicals, such as fungicides, dyes, and high-performance polymers like polyphenylene sulfide (PPS). PPS is a high-temperature engineering plastic that is used in a variety of demanding applications in the automotive, electronics, and aerospace industries.
