Nhanganyaya
Iyo organic compound ine kemikari formula C5H5N2O2. Iyo inowanzoita isina ruvara kune yakachenuruka yero crystalline yakasimba.
Mushonga wacho une mapoka maviri anoshanda, imwe ipyrazole ring uye imwe iboka re carboxylic acid rinoshanda. Ine pakati nepakati solubility uye inonyungudika mumvura uye zvakajairika organic solvents. Iyo methyl boka muchimiro chayo inoita kuti ive hydrophobic.
Sezvo heterocyclic compound, 5-methyl-ine zvakasiyana-siyana zvehupenyu hwehupenyu. Inoshandiswa zvakanyanya mukutsvaga kwemishonga uye kugadzirwa kwezvinodhaka, kazhinji sechinhu chakabikwa kana chepakati. Kunyanya kushandiswa kunosanganisira kuumbwa kwevhitamini B1 analogues, mishonga yezvipembenene, plavix inhibitors (mushonga unoshandiswa kurambidza kukura kwezvirimwa), nezvimwe zvakadaro.
Kugadzirira, 5-methyl-inogona kuwanikwa nekuita nitrogen atomu yepyrazole mhete ine methylating agent (eg methyl iodide). Iyi nzira inoitwa neN-methylation reaction, nzira yakajairika ndeyekuita kweiyo inoenderana nucleophile ine N-methyl reagent.
