Phenylureas fruits

N-2-Chloro-4-pyridmyl-N-phenylurea. CPPU [68157-60-8] (47) is a phenylurea plant growth regulator that has been used experimentally to increase fruit size in apples, grapes, kiwifruit, macadamia nuts (Macadamia temifolia)y cotton, small grains, and ornamentals (23).

Increasing research has developed several new noncaloric sweeteners the dihydrochalcone group of disaccharide, glycyrrhizin (licorice extract), especially its ammoniated derivative dulcin (4-ethoxy-phenylurea), the glycoprotein of miracle fruit and a polypeptide from a tropical fruit called the serendipity berry, said to be 3000 times sweeter than sucrose. Aspartame (C14H18N205) has been approved by FDA. 

Some carbamates (carbosulfan, benfuracarb, carbofuran, pirimicarb, diethofencarb, and diuron) and phenylurea pesticides (monuron and monolinuron) were sampled from different fruit juices by using 50-pm carbowax-templated resin (CW-TPR) and a 60-pm PDMS/DVB SPME fiber (Sagratini et al., 2007). The fiber desorption into the SPME-LC/MS interface chamber previously filled with 70% methanol and 30% water, was performed in static mode.

Herbicides derived from urea form a large group of chemical compounds widely used in agriculture to control weeds in cereal, vegetable, and fruit tree crops. On the basis of their chemical natures, use, and mode of action, substituted urea herbicides can be divided into two main groups — phenylureas and sulfonylureas.
