Description

Bromoxynilphenol is a key phenolic intermediate with significant utility in the synthesis of specialized agrochemicals. Its primary commercial value lies in its role as a precursor for the production of the selective herbicide bromoxynil, which is effective against broadleaf weeds in cereal crops. This compound is essential for manufacturers and formulators in the agricultural chemical industry seeking reliable, high-purity raw materials for crop protection solutions. Consistent quality and supply chain integrity are paramount for downstream product performance and regulatory compliance.

Application

• Primary Agrochemical Intermediate: Serves as the critical building block in the synthesis of the post-emergence herbicide bromoxynil (3,5-dibromo-4-hydroxybenzonitrile).
• Herbicide Formulation: Used in the manufacturing of various bromoxynil-based herbicide formulations, including emulsifiable concentrates (EC) and soluble liquid (SL) products.
• Research & Development: Employed in agricultural R&D for creating novel herbicidal compounds and studying structure-activity relationships (SAR) of nitrile herbicides.
• Chemical Synthesis: Functions as a versatile phenolic substrate in organic synthesis for introducing bromine and hydroxyl functional groups into more complex molecules.

Quality Control

Our Bromoxynilphenol is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity, typically ≥98% (by HPLC). Quality assurance includes comprehensive testing for identity, potency, and specific impurities. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, melting point, and residual solvents. We adhere to ISO guidelines and can support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizing agents and bases. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize exposure to moisture and air.
