2-Chlorobenzonitrile (2-CBN), also known as ortho-Chlorobenzonitrile (o-Chlorobenzonitrile) (CAS No. 873-32-5), is a key aromatic intermediate highly valued in the fine chemical and life science industries. Its market is structurally defined by its trifunctional nature, featuring an aromatic ring, a strategically placed chlorine atom, and a highly reactive nitrile group, making it an indispensable building block for complex, high-value molecules, particularly heterocyclic compounds.
This product will be delivered within 1-3 business days.
The 2-Chlorobenzonitrile industry is characterized by the following key features:
- Life Science and Biocidal Driver: The market is predominantly fueled by its crucial role in the synthesis of Isothiazolinone biocides (like BIT) and complex Pharmaceutical APIs (like Losartan and Valsartan). This dual dependency provides stable, non-cyclical demand from both public health/preservation and essential healthcare sectors.
- Standardized Production Process: The current mainstream manufacturing route is the ammoxidation method. This involves the catalytic reaction of the primary raw material, o-Chlorotoluene, with ammonia and oxygen. This process requires significant technical expertise in catalysis, high-temperature reaction management, and strict environmental control.
- High Geographic Concentration: China is the world's largest producer, consumer, and exporter of 2-CBN. This concentration reflects China's competitive advantage in fine chemical manufacturing, but it introduces significant supply chain risk for global users.
- Applications Driving 2-Chlorobenzonitrile Demand
- Biocides: Isothiazolinones
- Role: 2-CBN is a crucial starting material in the synthesis of Isothiazolinone biocides, such as Benzisothiazolinone (BIT), Isothiazol-3(2H)-one.
- Market Impact: These biocides are widely used for preservation in water-based products (paints, adhesives, sealants, slurries, metalworking fluids) and industrial water treatment. BIT is highly effective as an antimicrobial agent, driving consistent, volume-based demand for 2-CBN from the construction and industrial maintenance sectors.
- Trend: The shift toward waterborne and environmentally compliant products (which require strong in-can preservation) and the growth of industrial cooling tower/process water treatment ensure sustained demand for BIT and, consequently, 2-CBN.
- Pharmaceuticals:
- Role: 2-CBN is a key intermediate in the synthesis of complex pharmaceutical APIs, especially non-peptide angiotensin receptor blockers (ARBs).
- Key Products: It is used in the synthesis of major anti-hypertensive drugs, including Losartan and Valsartan. It is also an intermediate for the anti-malarial drug Nitroquine and various anti-inflammatory and antiseptic agents.
- Trend: The demand is high-purity driven, stable, and linked to the persistent global need for essential, high-volume generic drugs, particularly for chronic diseases like hypertension.
- Dyes and Pigments:
- Role: 2-CBN is used to synthesize dye intermediates, such as 2-cyano-4-nitroaniline.
- Market Impact: This derivative is a building block for azo dyes and specialty pigments, serving the textile, printing, and coatings industries.
- Trend: While smaller than the biocide and pharmaceutical sectors, this application provides steady, high-margin demand for specialty products.
- Others (Fine Chemicals):
- 2-CBN serves as a general intermediate for other specialty chemical syntheses, leveraging its reactive groups.

- Opportunities and Challenges
- Opportunities
- Structural Biocide Demand: The massive, structural global shift toward waterborne coatings and industrial water treatment guarantees sustained, volume-based demand for Isothiazolinone biocides like BIT, which rely on 2-CBN as a primary building block.
- Essential Pharmaceutical Market: The persistent need for high-volume, generic anti-hypertensive drugs like Losartan and Valsartan ensures a stable, high-purity demand segment that is largely insulated from economic volatility.
- Supply Chain Diversification: The new capacity planned in India by Aarti Industries (7,000 tpa) presents a critical opportunity for global buyers (especially API manufacturers) to secure supply outside of China, enhancing supply chain resilience and potentially stabilizing pricing.
- High-Purity Barrier to Entry: The technical complexity of the ammoxidation process, coupled with the need for high-purity product for pharmaceutical and premium biocide grades, provides a considerable barrier to entry, protecting established, technically competent producers.
- Challenges
- Severe Geopolitical and Supply Concentration Risk: The overwhelming concentration of global capacity in China poses a critical risk. Any trade barriers, regulatory changes, or environmental shutdowns in China could severely disrupt the global supply of 2-CBN and its downstream derivatives (BIT, Losartan).
- New Capacity Price Pressure: The planned 7,000 tpa expansion by Aarti Industries in India, while offering supply diversification, will add significant new volume to a relatively small global market. This may lead to intensified price competition and potential margin pressure, particularly in the competitive Asian merchant market.
- Raw Material Volatility: Production costs are highly sensitive to the pricing of the main precursor, o-Chlorotoluene, whose costs fluctuate with the broader petrochemical and commodity markets.
- Competition in Biocides: While BIT is effective, it faces competition from other classes of biocides (CMIT/MIT, DCOIT) and from non-chemical preservation methods, forcing 2-CBN derivative manufacturers to continuously innovate on cost and efficacy.
