The article conveys some information:
A series of novel pyrimidinamine derivatives containing phenyloxazole moiety I (R1 = H, 2-Cl, 4-CF3, etc.; R2 = Me, Et) was designed and synthesized, and their structures were characterized by 1H NMR, MS, and elemental analyses. The bioassay results displayed that some compounds exhibited remarkable insecticidal activities against Aphis fabae and Tetranychus cinnabarinus. Especially, I (R1 = 4-Me; R2 = Et) showed potent activity against A. fabae, superior to that of the com. insecticide, imidacloprid. In addition, I (R1 = 4-CF3; R2 = Et) showed potent activities against T. cinnabarinus, inferior to that of the com. insecticide spirotetramat. The structure-activity relationship study for the target compounds was also discussed. In the experiment, the researchers used Ethyl 3-oxopentanoate(cas: 4949-44-4Quality Control of Ethyl 3-oxopentanoate)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Quality Control of Ethyl 3-oxopentanoate
