S-(Carboxymethyl)-L-Cysteine ​​CAS 638-23-3 (Carbocisteine) Whakamātautau 98.5~101.0%

S-(Carboxymethyl)-L-Cysteine, ina whakamaroke, kaua e iti iho i te 98.5 paiheneti, kaua hoki e neke ake i te 101.0 ōrau o S-(Carboxymethyl)-L-Cysteine ​​(C5H9NO4S).
Whakaahuatanga: Kiriata ma, paura tioata ranei, he reka waikawa paku.
He iti noa te wairewa i roto i te wai, kare e rewa i roto i te waiwaro me te waikawa acettic glacial me te etera.Ka memeha ki te waikawa pūhaumāota waimeha me te konutai waihā TS.
Wairewa (H2O, g/100g): 0.13 (20 ℃)
Tautuhinga: Whakatauritea te awhiowhiotanga infrared absorption o te tauira ki tera o te paerewa ma te tikanga kōpae pāhare pāporo bromide.
Hurihuri Tau [α]20/D: Tauira maroke, C=10, pH6.0.I muri i te whakamaroke i te tauira, tangohia kia 5 karamu o te tauira.kia tika te pauna, memeha ki te 20ml wai me te wairewa konutai wai (13→100).I muri pH whakatika ki 6.0 ki 1mol/L 0.1mol/L waikawa pūmāota TS ranei, ka tāpiri wai ki te tika 50ml.
State of Solution (Transmittance): 1.0g i te 10ml o 1mol/L NaOH, spectrophotometer, 430nm, 10mm te matotoru pūtau.
Chloride (Cl): 0.36g, A-2, ref: 0.40ml o 0.01mol/L HCl
Haukinia (NH4): A-1
Putakawa (SO4): 1.2g, (2), ref: 0.50ml o 0.005mol/L H2SO4
Rino (Fe): 0.5g, (2), ref: 1.5ml o Iron Std.(0.01mg/ml)
Nga Kourarahi Taumaha (Pb): 2.0g, (2), ref: 2.0ml o Pb Std.(0.01mg/ml)
Arsenic (As2O3): 2.0g, (3), ref: 2.0ml o As2O3 Std.
Ētahi atu Acid Amino: 0.2mol / L NaOH, Tauira whakamatautau: 75μg, B-2-a mana;S-(Carboxymethyl)-L-Cysteine ​​0.15μg.I muri i te waahi o ia otinga ki runga i te pereti, ka whakawhanakehia te pereti i te wa kotahi
Ngaronga i te whakamaroke: i te 105 ℃ mo te 3 haora
Te toenga i runga i te mura (Sulfated): AJI Test 13
Te whakamatautau: Tauira maroke, 180mg, 0.1mol/L HCLO4 1ml=17.920mg C5H9NO4S.Whakarewa mo te 180mg o te tauira, i whakamarokehia i mua me te pauna tika, ki roto3ml o te waikawa formic, taapirihia kia rite ki te 15ml o te 0.1mol/L te waikawa perchloric, me te 50ml o te waikawa acetic glacial, me te titrate i te taikaha o te waikawa perchloric ki te 0.1mol/L konutai acetate,te whakatau i te pito mutunga potentiometrically.Whakaritehia he whakatau patea, me te whakatika tika.Ko ia ml o te 0.1mol/L te waikawa perchloric he rite ki te 17.920mg o C5H9NO4S.
pH: 1.0g i roto i te 10ml (Wairewa wai wairewa)
Te rohe rokiroki me nga ahuatanga e taunakitia ana: Ko nga ipu kikii te pupuri i te pāmahana rūma whakahaere (2 tau).
