2-(3-Chlorophenoxy)-propionic acid

2-(3-Chlorophenoxy)propionic acid (CAS 101-10-0), commonly known as Cloprop, is a high-purity chlorophenoxy carboxylic acid intermediate widely used in pharmaceutical synthesis, agrochemical development, plant growth regulator manufacturing, and fine chemical production. This compound features a chlorine substituent at the meta-position of the phenoxy group and a propionic acid side chain, making it a versatile building block for the development of complex organic molecules and active pharmaceutical ingredients (APIs). As a key intermediate in esterification, amide coupling, and functional group transformations, it exhibits excellent reactivity in nucleophilic substitution, cross-coupling reactions, and derivatization pathways. Our product is manufactured under strict quality control standards, ensuring a purity of ≥98%, making it ideal for pharmaceutical manufacturing, agrochemical formulation, medicinal chemistry research, and scale-up production. This compound is particularly valuable in the synthesis of plant growth regulators, herbicide intermediates, pharmaceuticals containing chlorophenoxy scaffolds, and specialty chemical precursors.
