I-Dimethyl Sulfoxide (DMSO) CAS 67-68-5

Iyini i-Dimethyl Sulfoxide (DMSO)?

I-Dimethyl sulfoxide, evame ukufushaniswa ngokuthi i-DMSO, iyincibilikisi ye-aprotic ephezulu kakhulu enefomula yamakhemikhali ethi C₂H₆OS. Ihlinzekwa njengoketshezi olucacile, olungenambala kanye ne-hygroscopic futhi luxubene ngokuphelele namanzi.

I-DMSO ihlanganisa i-solvency ephezulu, ukuguquguquka okuphansi nokuhambisana nezinto eziningi eziphilayo nezingaphili. Isetshenziselwa ukuhlanganiswa kwemithi kanye ne-agrochemical synthesis, ukucubungula i-polymer, ukwakhiwa kokuhlanza i-electronics, ukuhlanza izimboni, ukukhishwa kanye nokuhlaziywa kwelabhorethri.

Inombolo yayo ye-CAS ngu-67-68-5 futhi isisindo sayo samangqamuzana ngu-78.13 g/mol.

I-DMSO yezinga lezimboni akumele ichazwe ngokuzenzakalelayo njengebanga lemithi, inyumba, lomjovo, i-cell-culture noma ibanga le-cryopreservation. Lezi zinhlelo zokusebenza zidinga imikhiqizo ehlukene nemibhalo yokulawula.

Amaqiniso asheshayo we-DMSO

Amanani angenhla ayizici zereferensi. Ukucaciswa okusebenzayo kwe-AOZUN, ikhotheshini kanye Nesitifiketi Sokuhlaziya kufanele kunqume ikhwalithi yomkhiqizo onenkontileka.

Kungani I-DMSO Ibizwa Nge-Polar Aprotic Solvent?

I-DMSO i-polar enamandla kodwa ayinayo i-asidi ye-hydrogen ehlanganiswe nomoya-mpilo noma i-nitrogen. Ngakho-ke ihlukaniswa njenge-solvent ye-polar aprotic.

Iqembu layo le-sulfoxide likhiqiza i-dipole ye-molecular eqinile. Lokhu kuvumela i-DMSO ukuthi ixhumane nama-ion nama-molecule e-polar kuyilapho amaqembu ayo e-methyl ehlinzeka ngokuhambisana nezinhlanganisela eziningi zemvelo.

Lezi zakhiwo zinikeza i-DMSO uhla lokuncibilika olubanzi ngokungavamile futhi luyenze lusebenziseke njengendawo yokusabela, ukucubungula i-solvent kanye nengxenye yokwakhiwa kokuhlanza.

Isebenza kanjani i-DMSO njenge-Polar Aprotic Solvent?

Iqembu elinamandla le-sulphur-oksijeni eliphothuliwe ku-DMSO lingakwazi ukuzinzisa futhi lixazulule ama-ion amaningi nezinhlanganisela ze-polar, kuyilapho amaqembu e-methyl elisiza ukuthi lihlanganyele nezakhiwo eziphila ngaphansi kwe-polar. Le nhlanganisela ivumela i-DMSO ukuthi ihlakaze noma ihlakaze izinhlobonhlobo zikasawoti, ama-polymers, ama-resin, odayi kanye ne-organic intermediates.

Kungani Okuqukethwe Kwamanzi Kubalulekile

• Ukuthekelisa kwedokhumenti

• Ukuhlolwa komuntu wesithathu

• Ukuxhumana kwezobuchwepheshe ngesikhathi sokufaneleka

Ibanga lomkhiqizo, ukucaciswa, ukupakishwa, isimo sokulawula nokufaneleka kufanele kuqinisekiswe kwikhotheshini yokugcina kanye nenkontileka yokuthengisa.

Ulwazi okufanele lufakwe ku-DMSO RFQ yakho

Ukuze uthole ikhotheshini enembe kakhudlwana, hlinzeka:

• Igama lomkhiqizo kanye nenombolo ye-CAS

• Ibanga elidingekayo

• Ubumsulwa obuncane

• Ubuningi bokuqukethwe kwamanzi

• Umkhawulo wenani le-Acid

• Izidingo zokudlulisa amehlo

• Izidingo ze-UV-absorbance

• Imikhawulo ye-Trace-metal

• Isicelo esihlosiwe

• Oda inani

• Imfuneko yokupakisha

• Indawo oya kuyo

• Amadokhumenti adingekayo

• Imfuneko yesampula

• Isheduli yokulethwa

Uma ushintsha elinye ibanga le-DMSO, namathisela ukucaciswa kwalo kwamanje noma i-COA emele.

imibuzo ejwayelekile ukubuzwa

Iyini i-DMSO?

I-DMSO i-dimethyl sulfoxide, i-solvent ye-polar aprotic esetshenziswa kakhulu ekuhlanganiseni kwamakhemikhali, ukucutshungulwa kwe-polymer, i-electronics, ukuhlanzwa kwezimboni kanye nokuhlaziywa kwelabhorethri.

Ithini inombolo ye-CAS ye-DMSO?

Inombolo ye-CAS ngu-67-68-5.

Ithini ifomula ye-molecular ye-DMSO?

Ifomula yayo yamangqamuzana i-C₂H₆OS, futhi isisindo sayo samangqamuzana ngu-78.13 g/mol.

Ingabe i-DMSO iyancibilika emanzini?

Yebo. I-DMSO ixubene ngokuphelele namanzi.

Kungani i-DMSO icwebezela?

I-DMSO ehlanzekile icwebezela cishe ku-18.5°C. Ngakho-ke ingase ibe yiqhwa endaweni yokugcina impahla epholile noma ngesikhathi sokuhamba ebusika.

Ingabe i-DMSO eqandisiwe inephutha?

Akunjalo. Ngokuvamile ingabuyiselwa ngokufudumeza okulawulwayo, ukuncibilika okuphelele nokuxuba. Kufanele kulandelwe imiyalelo yomphakeli.

Ingabe i-DMSO iyavutha?

I-DMSO ine-flash point engaba ngu-87°C futhi ingase ichazwe njengoketshezi oluvuthayo. Kufanele igcinwe kude nemithombo yokuthungela nokushisa okungalawuleki.

Ingabe i-DMSO ingadlula esikhunjeni?

I-DMSO ingangena esikhunjeni futhi ingase ikhulise ukumuncwa kokungcola okuncibilikisiwe. Ukuthintana kwesikhumba okuqondile kufanele kugwenywe.

Ingabe i-DMSO yezimboni ingasetshenziselwa ukukhiqizwa kwemithi?

I-Industrial DMSO ingase isetshenziswe njengesixazululi esihlanganisayo lapho ifaneleka khona, kodwa akumelwe imelelwe njenge-USP, Ph. Eur., ibanga lomjovo noma elisizayo ngaphandle kokucaciswa okudingekayo kanye nekhwalithi yamadokhumenti.

Ingabe u-99.9% we-DMSO uyibanga le-HPLC ngokuzenzakalelayo?

Cha. Ibanga le-HPLC lidinga nezilawuli ezifanele zokumunca i-UV, izinsalela, amanzi nokungcola.

Ingabe i-99.9% yezinga le-elektroniki le-DMSO?

Cha. Ibanga le-elekthronikhi ngokuvamile lidinga ama-ion ensimbi aphansi kakhulu, izinhlayiya nezinsalela ezingaguquki ngaphezu kokuhlanzeka okuphezulu.

Ingabe i-DMSO yezimboni ingasetshenziselwa i-cryopreservation?

Akufanele kwenziwe umcabango onjalo. I-Cryopreservation idinga ibanga eliqeqeshwe ngokufanelekile elinobunyumba obufanele, i-endotoxin kanye nezilawuli zekhwalithi ye-biological.

Ingabe i-DMSO ingabe ingena esikhundleni se-DMF noma i-NMP?

Kungase kuhlolwe njengenye indlela, kodwa ukufaka esikhundleni se-solvent kudinga ukuhlolwa kokuncibilika, ukusebenza kokusabela, ukubuyisela, ukucwebezela, ukuhambisana kwemishini kanye nekhwalithi yomkhiqizo.

Yiziphi izici okufanele abathengi baziqhathanise?

Qhathanisa ukuhlanzeka, amanzi, i-asidi, iphoyinti lokucwebezela, inkomba ye-refractive, umbala, ukudlulisa, ukumunca kwe-UV, izinsalela ezingaguquki, ukungcola okuphilayo nezinsimbi zokulandelela.

I-DMSO kufanele igcinwe kanjani?

Yigcine ivalwe ngokuqinile, yomile futhi ivikelekile ezintweni ezingahambelani. Izinga lokushisa lesitoreji kufanele lihlanganise iphoyinti layo lekristalu elicishe libe ngu-18.5°C.

Ingabe i-AOZUN inganikeza isampula ye-DMSO kanye ne-COA?

Ukutholakala kwesampula neqoqo-document kungaxoxwa ngakho ngesikhathi sekhotheshini. Faka ibanga elidingekayo, isicelo, ukucaciswa kanye nendawo ekuyiwa kuyo embuzweni.

Cela ikhotheshini ye-DMSO

Xhumana ne-AOZUN ukuze uthole amanani entengo ye-dimethyl sulfoxide, imininingwane, ukupakishwa kanye nolwazi lokuthekelisa.

Sithumelele izinga lakho elidingekayo, ubumsulwa, umkhawulo womswakamo, isicelo, ubungako, ukupakishwa, indawo kanye nesheduli yokulethwa. Ithimba lethu lizobuyekeza imfuneko futhi liqinisekise ukucaciswa okufanele kwezentengiso.
