3,4-Dichlorobenzonitrile (CAS 6574-99-8) is a vital aromatic nitrile that serves as a cornerstone intermediate in numerous chemical synthesis processes. Its unique structural features, characterized by two chlorine atoms and a nitrile group attached to a benzene ring, make it a versatile compound for creating a wide array of downstream products. Understanding its synthesis routes and diverse applications is crucial for professionals in the chemical manufacturing sector.

The synthesis of 3,4-Dichlorobenzonitrile typically involves several established chemical pathways. One common method is the Sandmeyer reaction, which converts 3,4-dichloroaniline into the corresponding benzonitrile through diazotization followed by reaction with copper(I) cyanide. Alternatively, methods involving the dehydration of 3,4-dichlorobenzamide or the cyanation of 3,4-dichlorobenzene derivatives can also be employed. Manufacturers focus on optimizing these processes to achieve high yields and purity, often exceeding 99% for commercial applications.

The primary applications of 3,4-Dichlorobenzonitrile are found in two major sectors: agrochemicals and pharmaceuticals. In agrochemicals, it is a key precursor for synthesizing various herbicides, contributing to more efficient and targeted weed control in modern agriculture. For instance, its use in producing selective pre-emergent herbicides is well-documented. When businesses look to buy 3,4-dichlorobenzonitrile for these applications, they prioritize suppliers who can guarantee consistent quality and scalability.

In the pharmaceutical industry, 3,4-Dichlorobenzonitrile functions as a valuable intermediate for the synthesis of Active Pharmaceutical Ingredients (APIs) and novel drug candidates. Its structure can be readily modified to incorporate various functional groups, enabling the construction of complex organic molecules with desired pharmacological activities. This makes it an indispensable compound for pharmaceutical research and development, as well as for the commercial production of established drugs. A reliable pharmaceutical intermediate supplier is crucial for this segment.

The demand for high-purity 3,4-Dichlorobenzonitrile is on the rise, driven by stricter quality requirements in end-use industries. Manufacturers in China are increasingly investing in advanced synthesis technologies and stringent quality control systems to meet these demands. For companies seeking to source this chemical, understanding the price of 3,4-dichlorobenzonitrile in relation to purity and volume is important. Partnering with a trusted 3,4-dichlorobenzonitrile manufacturer ensures a stable supply of this critical building block for diverse chemical manufacturing needs.
