Overview
Phenylurea, also known as N-Phenylurea, is an organic compound with the molecular formula C7H8N2O. It is a white crystalline solid primarily used as a herbicide in agriculture. The compound is known for its effectiveness in controlling weeds by inhibiting photosynthesis in plants. Phenylurea is also utilized as an intermediate in the synthesis of various chemicals, including pharmaceuticals and dyes. Its stable nature and solubility in common solvents make it a versatile compound in industrial applications.
Physical and Chemical Properties
Phenylurea exhibits a melting point range of 147-149 °C and a density of 1.23 g/cm³. It is soluble in water, ethanol, and acetone, which facilitates its use in liquid formulations. The compound is stable under normal conditions but may decompose at high temperatures or in the presence of strong acids or bases. Key chemical properties include its herbicidal activity, which stems from its ability to disrupt the photosynthetic process in plants. This makes it particularly effective against a wide range of weed species.
Main Applications
The primary application of phenylurea is as a herbicide in agriculture. It is used to control weeds in crops such as cotton, soybeans, and cereals. Its effectiveness and relatively low toxicity to mammals make it a popular choice among farmers. In addition to its agricultural uses, phenylurea serves as an intermediate in the synthesis of other chemicals. It is employed in the production of pharmaceuticals, dyes, and other specialty chemicals, highlighting its importance in various industrial sectors.
Safety and Storage
Phenylurea should be handled with care to avoid inhalation or skin contact. Personal protective equipment, including gloves and goggles, is recommended when working with this chemical. In case of exposure, rinse the affected area with plenty of water and seek medical attention if necessary. Storage conditions for phenylurea include keeping it in a cool, dry place away from direct sunlight. Properly sealed containers are essential to prevent moisture absorption and degradation of the compound.
B2B Procurement Guide
When procuring phenylurea, B2B buyers should verify the supplier's credentials and request a Certificate of Analysis (COA) to ensure product purity. The Material Safety Data Sheet (MSDS) should also be reviewed to understand handling and storage requirements. Prices for phenylurea typically range from $20 to $50 per kilogram, depending on purity and order quantity. Bulk purchases may qualify for discounts, so it is advisable to negotiate with suppliers for better terms.
