In the expansive world of chemical synthesis, certain compounds serve as indispensable building blocks, enabling the creation of more complex and valuable substances. Among these critical components is 3-phenoxybenzaldehyde cyanohydrin, identified by its CAS number 52315-06-7. Also known by synonyms such as (S)-2-hydroxy-(3-phenoxy)phenylacetonitrile, (S)-(cyano)(3-phenoxyphenyl)methanol, and (3-Phenoxyphenyl)glycolonitrile, this compound plays a pivotal role, particularly in the agrochemical industry.

Chemically, 3-phenoxybenzaldehyde cyanohydrin is characterized by its molecular formula C14H11NO2 and a molecular weight of 225.24300. Its physical state is typically a yellow to light brown viscous liquid. Key physical and chemical properties include a density of 1.22g/cm3, a boiling point of 399.8ºC at 760mmHg, a flash point of 195.6ºC, and an index of refraction of 1.606. These precise characteristics are vital for its effective handling and integration into various synthetic processes.

Ensuring the quality of such an intermediate is paramount. Reputable manufacturers typically provide 3-phenoxybenzaldehyde cyanohydrin with stringent specifications. A high assay of ≥95.0% is standard, accompanied by strict limits on impurities such as unreacted MPBAD (≤2.0%) and free CN (≤1.0%). Such rigorous quality control guarantees performance and consistency in downstream applications. For packaging, it is commonly available in 200 kg drums, with flexibility for customer-specific requirements. Proper storage in a cool, ventilated place is essential to maintain its stability and integrity.

The primary application of 3-phenoxybenzaldehyde cyanohydrin lies in its function as a crucial intermediate for the synthesis of a range of highly effective synthetic pyrethroid insecticides. These include Decamethrin (CAS: 52918-63-5), Cymperator (CAS: 52315-07-8), Phenvalerate (CAS: 51630-58-1), Flucythrinate (CAS: 70124-77-5), Cyhalothrin (CAS: 91465-08-6), and Cyphenothrin (CAS: 39515-40-7). Its unique chemical structure makes it an ideal precursor, contributing to the insecticidal efficacy and stability of these end products.

Understanding the concept of a "reaction intermediate" is key to appreciating the value of compounds like 3-phenoxybenzaldehyde cyanohydrin. In chemistry, an intermediate is a substance that is generated during one step of a complex chemical reaction and subsequently consumed in a later step. Unlike transient transition states, which represent energy peaks and cannot be isolated, intermediates exist at energy minima along the reaction pathway and can be sufficiently stable to be detected or even isolated under specific conditions. They are integral to multi-step reaction mechanisms, allowing chemists to control the flow of a reaction and build intricate molecular architectures step-by-step. This controlled, sequential transformation is particularly critical in the manufacturing of pharmaceuticals, agrochemicals, and specialty chemicals, where precise molecular structures and high purity are non-negotiable.

For those seeking to incorporate this essential compound into their production lines, finding a reliable 3-phenoxybenzaldehyde cyanohydrin manufacturer is crucial. Leading suppliers emphasize not only product quality but also consistency and dependable delivery. When considering where to buy 3-phenoxybenzaldehyde cyanohydrin, it is advisable to inquire about bulk price options and ensure the supplier can meet specific volume requirements. A transparent and efficient supply chain is vital for seamless operations in the agrochemical and related industries. Trustworthy partners are those who can provide comprehensive product data, timely logistics, and competitive purchase terms for this critical intermediate, ensuring the continuous and effective production of valuable end products.
