Overview
2-(Chlorophenoxy)propionic acid is a chlorinated phenoxy herbicide widely used in agriculture for selective weed control. It belongs to the phenoxy herbicide family and is valued for its systemic action, which allows it to be absorbed by plants and translocated to growing points. The compound is particularly effective against broadleaf weeds while leaving grasses relatively unharmed. Developed as part of the phenoxy herbicide group, 2-(Chlorophenoxy)propionic acid has been utilized in crop protection for decades. Its chemical structure includes a chlorophenoxy group attached to a propionic acid backbone, contributing to its herbicidal activity. The compound is commonly formulated as a soluble concentrate or emulsifiable concentrate for agricultural applications.
Physical and Chemical Properties
2-(Chlorophenoxy)propionic acid typically appears as a white to off-white crystalline powder with a melting point of approximately 120-122°C. Its molecular weight is 200.62 g/mol, and it is characterized by the molecular formula C9H9ClO3. The compound is soluble in common organic solvents such as ethanol and acetone but has limited solubility in water. The chemical exhibits stability under normal storage conditions but may degrade when exposed to extreme temperatures or prolonged sunlight. Its herbicidal activity is attributed to its ability to mimic natural plant hormones, disrupting normal growth processes in susceptible weeds. The chlorinated aromatic ring enhances its biological activity and selectivity.
Main Applications
The primary application of 2-(Chlorophenoxy)propionic acid is in agriculture as a selective herbicide for controlling broadleaf weeds in cereal crops, turf, and pasture systems. It is particularly effective against weeds such as chickweed, clover, and plantain while being less harmful to grasses. The compound is often used in post-emergence applications, where it is absorbed by foliage and translocated throughout the plant. In addition to its herbicidal uses, 2-(Chlorophenoxy)propionic acid has been studied for its potential as a plant growth regulator. It can influence various growth processes in plants, including cell elongation and division. Some formulations combine this compound with other herbicides to broaden the spectrum of weed control and enhance efficacy.
Safety and Storage
When handling 2-(Chlorophenoxy)propionic acid, appropriate safety measures should be taken to minimize exposure. Workers should wear protective gloves, eyewear, and clothing to prevent skin and eye contact. Inhalation of dust or vapors should be avoided, and adequate ventilation is recommended in areas where the chemical is handled or stored. Storage conditions are critical for maintaining the chemical's stability. It should be kept in a cool, dry place away from direct sunlight and moisture. Containers should be tightly sealed to prevent contamination and degradation. In case of spillage, absorbent materials should be used, and contaminated areas should be cleaned promptly following local regulations for chemical disposal.
B2B Procurement Guide
For B2B buyers, sourcing 2-(Chlorophenoxy)propionic acid requires attention to several key factors. First, verify the CAS number (101-10-0) to ensure the correct chemical is being purchased. Suppliers should provide certificates of analysis (CoA) confirming the purity and composition of the product. Procurement professionals should assess supplier reliability, including compliance with agricultural chemical regulations in the target market. Bulk purchases may offer cost advantages, but storage capacity and shelf life should be considered. It's advisable to request samples for quality testing before large-scale orders. Additionally, buyers should be aware of any regional restrictions or licensing requirements for herbicide use.
