Overview
Chlorfenuron, also known as Forchlorfenuron or CPPU, is a synthetic plant growth regulator widely used in agriculture. It belongs to the phenylurea class of compounds and is known for its ability to promote cell division and fruit enlargement. Chlorfenuron is particularly effective in improving the size and quality of fruits such as kiwis, grapes, and melons. Its application has revolutionized modern agriculture by significantly increasing crop yields and improving the uniformity of fruit size. However, its use is regulated in many countries to ensure safe and responsible application.
Physical and Chemical Properties
Chlorfenuron is a white to off-white crystalline powder with a molecular weight of 247.68 g/mol. It has a melting point of approximately 165-170°C and is slightly soluble in water but more soluble in organic solvents like acetone and ethanol. The compound is stable under normal storage conditions but should be protected from moisture and direct sunlight. Its chemical structure includes a phenylurea moiety, which is responsible for its biological activity. The presence of a chlorine atom enhances its stability and efficacy as a plant growth regulator.
Main Applications
Chlorfenuron is primarily used in agriculture to promote fruit setting and enlargement. It is applied to crops such as kiwifruit, grapes, melons, and cucumbers to improve yield and quality. The compound works by stimulating cell division, leading to larger and more uniform fruits. In addition to its use in fruit production, Chlorfenuron is also employed in horticulture for seedless fruit production and in tissue culture to promote callus growth. Its versatility makes it a valuable tool for farmers and researchers alike.
Safety and Storage
Chlorfenuron should be handled with care to avoid health risks. Personal protective equipment (PPE), including gloves and masks, should be worn during handling and application. The compound should be stored in a cool, dry place away from direct sunlight and moisture to maintain its stability. Proper disposal methods should be followed to prevent environmental contamination. Regulatory guidelines for agricultural chemicals must be adhered to ensure safe and responsible use. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety instructions.
B2B Procurement Guide
When procuring Chlorfenuron, it is essential to source from reputable suppliers who comply with agricultural chemical regulations. Request a Certificate of Analysis (COA) to verify the purity and quality of the product. The Material Safety Data Sheet (MSDS) should also be reviewed for safety and handling guidelines. Price ranges for Chlorfenuron typically vary between $50 and $100 per kilogram, depending on purity and supplier. Bulk purchases may offer cost savings, but ensure that storage conditions are adequate to maintain product integrity. Always consider regulatory requirements in your region before procurement.
