Taurine CAS 107-35-7 Assay 99.0 ~ 101.0% Warshada Tayada Sare

Taurine (CAS: 107-35-7) Habka Tijaabada JP
Taurine, marka la qalajiyo, waxay ka kooban tahay wax aan ka yarayn 99.0% oo aan ka badnayn 101.0% ee C2H7NO3S.
Sharaxaada Taurine waxay u dhacdaa sida kiristaalo aan midab lahayn ama cad, ama budo crystalline cad.
Waxay ku milmi kartaa biyaha, iyo ficil ahaan aan lagu milmi karin ethanol (99.5).
pH ee xalka loo diyaariyey iyadoo lagu milmay 1.0 g oo Taurine ah 20 mL oo biyo cusub la karkariyey oo la qaboojiyey waa inta u dhaxaysa 4.1 iyo 5.6.

(5) Biraha culus <1.07>- Ku sii wad 2.0 g oo Taurine ah sida waafaqsan Habka 1, oo samee tijaabada.Ku diyaari xalka xakamaynta 2.0 mL ee Xalinta Lead Heerka (aan ka badnayn 10 ppm).
(6) Iron <1.10>-Ku diyaari xalka tijaabada leh 2.0 g of Taurine sida waafaqsan Habka 1, oo samee tijaabada sida ku cad Habka A. Diyaari xalka xakamaynta 2.0 mL ee Xalka Birta caadiga ah (aan ka badnayn 10 ppm).
(7) Walxaha laxidhiidha-Ku mil 1.0 g oo Taurine ah 50 ml oo biyo ah, una isticmaal xalkan sida xalka muunada.Tuub 1 ml oo ah xalka muunada, kuna dar biyo si aad u samayso 50 ml oo sax ah.Dhuumaha 1 mL ee xalkan, ku dar biyo si aad u samayso 10 ml oo sax ah, oo u isticmaal xalkan sida xalka caadiga ah.Ku samee tijaabada xalalkan sida lagu faray Chromatography-ka khafiifka ah <2.03>.Bar 5mL mid kasta oo ka mid ah muunadda muunada iyo xalalka caadiga ah saxan jel silica ah oo loogu talagalay chromatography-ka khafiifsan.Ku samee saxanka isku dhafka biyaha, ethanol (99.5), 1-butanol iyo acetic acid (100) (150: 150: 100: 1) ilaa masaafo qiyaastii 10 cm ah, oo hawo-qallaji saxanka.Ku buufi si siman ninhydrin-butanol TS saxanka, oo kuleyl 105 ℃ 5 daqiiqo: barta kale ee aan ahayn barta mabda'a ee xalka muunada ma aha wax ka badan hal dhibic, mana aha mid ka daran barta xalka caadiga ah. .
Luminta qallajinta <2.41> In aan ka badnayn 0.20% (1 g, 105 ℃, 2 saacadood).
Hadhaaga dabka <2.44>Kama badna 0.1% (1 g).
Assay Si sax ah u miisaan qiyaastii 0.2 g oo Taurine ah, oo hore loo qalajiyey, ku milmi 50 mL oo biyo ah, ku dar 5 mL oo xal formaldehyde ah, iyo titrate <2.50>oo leh 0.1 mol/L sodium hydroxide VS (titration potentiometric).U samee go'aan madhan si la mid ah, oo samee wixii sixid ah oo lagama maarmaan ah.
ML kasta oo ah 0.1 mol/L sodium hydroxide VS ＝12.52 mg ee C2H7NO3S
