Katundu ndi kukhazikika

Chogulitsachi sichikhala chokhazikika ndipo chimatha kusungunuka ndi hydrolyzed mu ammonia ndi urea mu yankho lamadzimadzi, motero kuwopsa kwake ndikofanana ndi kwa urea. Guanidine ndi zotumphukira zake zimakhala zowopsa kwambiri kuposa urea.

Cholinga: 1. Itha kugwiritsidwa ntchito ngati chapakatikati pa mankhwala, mankhwala ophera tizilombo, utoto ndi kaphatikizidwe kena kazinthu zina. Itha kugwiritsidwa ntchito kupanga 2-Aminopyrimidine, 2-amino-6-methylpyrimidine ndi 2-amino-4,6-dimethylpyrimidine. Ndi wapakatikati popanga sulfadiazine, sulfamethylpyrimidine ndi sulfadimidine.

2. Guanidine hydrochloride (kapena guanidine nitrate) imagwirana ndi ethyl cyanoacetate kupanga 2,4-diamino-6-hydroxypyrimidine, yomwe imagwiritsidwa ntchito kupangira mankhwala ochepetsa kuchepa kwa magazi m'thupi folic acid. Itha kugwiritsidwanso ntchito ngati antistatic wothandizira ulusi wopanga.

3. Itha kugwiritsidwanso ntchito ngati protein denaturant.

1. Monga wolimba mwamphamvu poyesera kutulutsa RNA yonse. Yankho la Guanidine hydrochloride limatha kusungunula mapuloteni, kuwononga mawonekedwe am'magulu, kuwonongeka kwa protein ya nyukiliya, kusiyanitsa ndi nucleic acid, komanso, RNase itha kuchititsidwa ndi kuchepetsa wothandizila monga guanidine hydrochloride.

njira yopangira

Pogwiritsa ntchito dicyandiamide ndi ammonium salt (ammonium chloride) ngati zopangira, guanidine hydrochloride yosakongola idapezeka posungunuka pa 170-230 ℃, ndipo zomwe zidamalizidwa zidapezedwa poyenga.

Lumikizanani ndi olamulira

1. Osapumira mpweya
