Electro Plating, High-Purity Solvents

O-Chlorobenzaldehyde Solution (OCBA)

O-Chlorobenzaldehyde, designated by CAS number 89-98-5, is a significant organic compound and an aromatic aldehyde primarily utilized as a versatile intermediate in various chemical syntheses. Structurally, it consists of a benzene ring substituted with both a formyl group and a chlorine atom at the ortho position. As a liquid solution, it appears as a clear, colorless to pale yellow fluid characterized by a distinctive, pungent odor. This reactive building block is indispensable in the production of agrochemicals, pharmaceuticals, and dyestuffs. Its chemical reactivity is driven by the electron-withdrawing nature of the chlorine substituent, which influences the nucleophilic addition reactions at the carbonyl center. Industrially, it is produced via the hydrolysis of o-chlorobenzotrichloride or the selective oxidation of o-chlorotoluene. Due to its corrosive nature and potential for irritation, handling requires rigorous safety protocols including protective equipment and adequate ventilation. It remains a cornerstone reagent for synthesizing diverse complex molecules across industries.
