Introduction to 5-Chloro-2-methylbenzamide (CAS No. 1028252-11-0)

5-Chloro-2-methylbenzamide, identified by the Chemical Abstracts Service Number (CAS No.) 1028252-11-0, is a significant compound in the realm of pharmaceutical and biochemical research. This molecule, featuring a chlorinated aromatic ring and an amide functional group, has garnered attention due to its structural versatility and potential applications in medicinal chemistry. The presence of both electron-withdrawing and electron-donating substituents in its benzene core makes it a valuable scaffold for designing novel bioactive molecules.

The chemical structure of 5-Chloro-2-methylbenzamide consists of a benzene ring substituted with a chlorine atom at the 5-position and a methyl group at the 2-position, connected to an amide moiety. This specific arrangement imparts unique electronic and steric properties, enabling interactions with biological targets in diverse ways. The chlorine atom enhances electrophilicity, making the molecule susceptible to nucleophilic substitution reactions, while the methyl group influences the overall shape and polarity of the molecule, affecting its binding affinity to proteins.
