I-D-Cysteine Hydrochloride Monohydrate (HD-Cys-OH·HCl·H2O) (CAS: 32443-99-5) AJI 97 Indlela yoVavanyo
I-D-Cysteine Hydrochloride Monohydrate, xa yomisiwe, iqulethe ngaphantsi kweepesenti ze-98.5 kwaye ingabi ngaphezu kwe-101.0 ipesenti ye-D-Cysteine Hydrochloride (C3H7NO2S·HCl).
Ukunyibilika (H2O, g/100g): malunga nama-67 (25℃)
Ukuchonga: (1) Kwi-5ml yesisombululo se-D-Cysteine Hydrochloride Monohydrate (1→ 1000) yongeza i-0.5ml ye-pyridine kunye ne-1ml ye-1% isisombululo se-ninhydrin kunye nokushisa imizuzu emi-3;umbala omfusa okanye omfusa omdaka uveliswa.
(2) Kwi-5ml yesisombululo se-D-Cysteine Hydrochloride Monohydrate (1→ 1000) kunye ne-2ml ye-10% isisombululo se-sodium hydroxide kunye namaconsi amabini e-5% isisombululo se-sodium nitroferricyanide;umbala obomvu-mfusa uveliswa.
(3) Thatha iimali ezincinci zesampulu yovavanyo kucingo lobhedu.Ukutshisa kwilangatye legesi, emva koko kuveliswa umbala oluhlaza (i-Beilstein reaction).
