Overview

2-(4-chloro-2-methylphenoxy)propanoic acid (CAS 7085-19-0) is an organochlorine compound with herbicidal properties and significant environmental persistence. This synthetic phenoxyalkanoic acid derivative represents an important class of selective herbicides widely used in agricultural and industrial applications. With the molecular formula C10H11ClO3 and a molecular weight of 214.64 g/mol, this compound exhibits the characteristic structure of phenoxy acid herbicides, featuring a chlorinated aromatic ring linked to a propanoic acid moiety through an ether bridge. The compound is classified under multiple hazard categories, requiring careful handling protocols. It presents acute toxicity concerns (Acute Tox. 4), causes skin irritation (Skin Irrit. 2), and severe eye damage (Eye Dam. 1), necessitating appropriate personal protective equipment during handling. Of particular concern is its environmental impact, classified as both acutely and chronically toxic to aquatic life (Aquatic Acute 1, Aquatic Chronic 1), which demands strict containment and disposal procedures. Structurally related to other phenoxy herbicides such as 2-(4-chloro-2-methylphenoxy)acetic acid, this compound shares similar mechanisms of action while offering distinct selectivity profiles. The propanoic acid backbone differentiates it from acetic acid derivatives, potentially affecting its bioactivity and environmental fate. Primary industrial applications include selective weed control in cereal crops, turf management, and specialized agricultural formulations. The compound is also utilized in research applications for herbicide development and plant growth regulation studies. Its effectiveness against broadleaf weeds while maintaining selectivity for grass crops makes it valuable in integrated pest management systems. OYSI maintains strategic inventory levels of 2-(4-chloro-2-methylphenoxy)propanoic acid to support European customers across agricultural, research, and specialty chemical sectors.
