2-Chloro-5-tert-butylbenzaldehyde丨CAS 1160574-90-2

2-Chloro-5-tert-butylbenzaldehyde (CAS 1160574-90-2) is an aromatic aldehyde derivative mainly used as a key intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. Its chloro and tert-butyl substituents, combined with the reactive aldehyde group, make it a versatile building block for designing structurally diverse compounds. In pharmaceutical research, it is employed in the synthesis of drug candidates, particularly those requiring aromatic frameworks with steric bulk and electron-withdrawing substituents. In agrochemicals, it contributes to the development of herbicides, fungicides, and insecticides by serving as a precursor for bioactive aromatic derivatives. Additionally, it is used in specialty chemical production for creating advanced materials, fragrances, and functionalized aromatic compounds with tailored reactivity.

The benefits of 2-chloro-5-tert-butylbenzaldehyde stem from its structural versatility and chemical reactivity. The aldehyde group allows for a wide range of transformations, including condensation, reduction, and oxidation, while the tert-butyl group provides steric protection that enhances stability and influences the biological activity of derivatives. The chloro substituent serves as a reactive handle for further substitution or cross-coupling reactions, facilitating the creation of complex molecules. This combination of features makes it an efficient and adaptable intermediate that supports high-yield syntheses and the design of compounds with desirable physical, chemical, and biological properties.
