Description

Fenoxaprop-P CAS NO 113158-40-0 is the herbicidally active (R)-enantiomer of fenoxaprop-ethyl, representing a high-purity, optically pure aryloxyphenoxypropionate herbicide. This compound matters for its superior efficacy and environmental profile, offering targeted post-emergence control of grassy weeds in broadleaf crops at significantly reduced application rates compared to racemic mixtures. It is critically needed by agricultural chemical formulators and producers serving the global crop protection industry, particularly for use in wheat, barley, soybeans, and rice.

Application

• Selective Herbicide Formulation: Primary active ingredient in post-emergence herbicide formulations for control of annual and perennial grassy weeds.
• Cereal Crop Protection: Key component in products for wheat, barley, and rye, targeting weeds like wild oats, black-grass, and ryegrass.
• Broadleaf Crop Integration: Used in soybean, peanut, and other legume crops for managing grass weed competition without harming the crop.
• Rice Paddy Management: Applied in rice fields for effective control of Echinochloa crus-galli (barnyard grass) and other problematic grasses.
• Turf and Ornamental Management: Incorporated into specialty products for fine turfgrass and ornamental plantings where selective grass control is required.
• Industrial Vegetation Control: Used in non-crop areas and right-of-way management as part of a broader vegetation control strategy.
• Technical Material for Synthesis: Serves as a high-purity intermediate for the synthesis of fenoxaprop-P-ethyl, the common esterified commercial form.

Quality Control

Our Fenoxaprop-P is manufactured under a strict quality management system to ensure batch-to-batch consistency and high optical purity. Quality control adheres to relevant agrochemical industry standards, with critical parameters including chiral purity (enantiomeric excess), chemical assay, and impurity profiles monitored via advanced analytical techniques. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials such as oxidizing agents. The container must be kept tightly closed to prevent moisture absorption.
