The synthesis of modern agrochemicals, particularly advanced insecticides, is a complex but critical process that underpins global food production. For manufacturers specializing in pyrethroids, a class of highly effective synthetic insecticides, the availability of high-quality intermediates is non-negotiable. This article explores the role of 2-(4-chlorophenyl)-3-methylbutanenitrile (CAS 2012-81-9) as a pivotal intermediate in this synthesis and highlights key considerations for procurement. For those looking to buy this compound, understanding its chemical journey is crucial.

The journey from basic chemical building blocks to potent insecticides involves intricate synthesis pathways. 2-(4-chlorophenyl)-3-methylbutanenitrile is a prime example of such an intermediate. Its structure contains the essential chlorophenyl moiety and a nitrile group that can be readily transformed into other functional groups. In the synthesis of pyrethroids like Phenvalerate, this intermediate is typically converted into the corresponding 3-methyl-2-(4-chlorophenyl)butyric acid. This conversion often involves hydrolysis of the nitrile group to a carboxylic acid. Subsequently, this acid is esterified with an appropriate alcohol component to form the final insecticidal ester. The purity of the starting nitrile, generally required to be ≥99.0%, directly impacts the efficiency of these subsequent steps and the quality of the final product.

For R&D scientists and process engineers, the physical and chemical properties of 2-(4-chlorophenyl)-3-methylbutanenitrile are vital. As a colorless to light yellow transparent liquid, it is amenable to various standard chemical processing techniques. Its molecular weight of 193.67300 and density of 1.086 g/cm³ are important parameters for reactor loading and material handling. When companies aim to purchase this intermediate, they are seeking a product that ensures consistent reaction kinetics and minimal side-product formation. This is why reliable suppliers who can provide detailed technical data sheets and Certificates of Analysis are highly valued.

Procurement managers often find that sourcing critical intermediates like CAS 2012-81-9 from China offers a strategic advantage in terms of both cost and availability. When searching for ‘pesticide intermediates for sale’ or specific product names, it's beneficial to engage with established chemical manufacturers. These suppliers typically possess large-scale production capacities and well-developed quality control systems. Establishing a partnership with a reputable Chinese manufacturer means obtaining competitive pricing for your bulk purchases, ensuring reliable delivery schedules, and maintaining a robust supply chain for your manufacturing operations. Always request a quote and inquire about bulk purchase discounts.

In essence, the chemical synthesis of pyrethroid insecticides relies heavily on intermediates like 2-(4-chlorophenyl)-3-methylbutanenitrile. Understanding its role in the synthetic pathway and prioritizing the sourcing of high-purity material from trusted manufacturers are key to successful agrochemical production. By making informed decisions during the procurement process, companies can ensure the development and availability of effective pest control solutions.
