Ukuhlanzeka okuphezulu 99%min Allantoin CAS 97-59-6
Igama Lekhemikhali: 5-Ureidohydantoin; I-Allantion
Isibizo: (2,5-dioxo-4-imidazolidinyl) -urea
I-Molecular Formula: 158.12
1. Izakhiwo
umkhiqizo ohlanzekile awunabo ubuthi, awunaphunga futhi awucasuli ikristalu elimhlophe, mp 226-240°C; encibilika emanzini ashisayo, utshwala kanye nesisombululo se-sodium hydroxide diluted; inyibilika kancane emanzini ezinga lokushisa elivamile kanye notshwala, okungancibiliki ku-ether ne-chloroform; I-pH-value yesisombululo sayo se-aqueous esigcwele (i-concentration 0.6%) ngu-5.5; ezinzile nge-PH 4-9; uzinzile kusisombululo esingewona amanzi kanye nomoya owomile; ingabola ngokubilisa isixazululo se-alkali nangaphansi kwe-insolation.
2. Sebenzisa:
Kungamakhemikhali abalulekile asetshenziswa kabanzi ekhemisi, embonini ekhanyayo, ezolimo, amakhemikhali ansuku zonke kanye ne-bio-engineering:
1. Ekhemisi: kungakhuphula ukukhula kwamangqamuzana nokuphola kwesilonda; futhi ngempumelelo ekwelapheni i-xerodermia, i-osteomyelitis ne-hepatocirrhosis njll.
2. Ezimonyoni: ingagcina umswakama wesikhumba; isetshenziswa kabanzi ku-freckles cream, i-shampoo, insipho, umuthi wokuxubha njll.
3. Kwezolimo: isetshenziswa njengokulawula ukukhula kwezitshalo ukolweni, irayisi, imifino kanye netiye.
