Acetonitrile ya fito ne don ƙarancin danko, babban dielectric akai-akai, da kuma bayyanar UV (ƙananan ɗaukar nauyi a 190-230 nm a cikin manyan ma'auni mai tsabta), yana sa ya dace don aikace-aikacen buƙatu.
HPLC da LC-MS Wayar hannu Phase : An fi son eluent a cikin jujjuya-lokaci babban aikin chromatography na ruwa saboda ƙarancin danko, kyakkyawan siffar kololuwa, da ƙarancin yankewar UV (~ 190 nm).
Pharmaceutical Synthesis da Tsarkakewa : An yi amfani da shi azaman ƙoshin amsawa, matsakaicin hakar, da sauran ƙarfi crystallization a masana'antar API da haɗin peptide.
Organic Chemistry : Polar aprotic sauran ƙarfi don halayen nucleophilic, Grignard reagents, da hakar mai, hydrocarbons, da samfuran halitta.
Chemistry na Nazari : Yana narkar da gishiri, kwayoyin halitta na polar, kuma yana goyan bayan binciken spectroscopy, electrochemistry, da binciken baturi.
Hanyoyin Masana'antu : haɓakar Butadiene, samar da sinadarai na musamman, kuma azaman farawa don wasu tsaka-tsaki.
Acetonitrile din mu ya hadu ko ya wuce ACS, USP/NF, da Ph. Eur. ƙayyadaddun bayanai na reagent, tare da tsauraran iko akan ƙazanta kamar ruwa (≤0.01% a cikin busassun maki), acidity, da gurɓatawar UV. Kunshe ƙarƙashin inert iskar gas don kula da inganci, yana tabbatar da sakamakon da za a iya maimaitawa a cikin m gradient HPLC, UHPLC, da kuma haɗakar danshi. Akwai a cikin maki daban-daban: HPLC gradient grade, LC-MS grade, anhydrous, da matsananci-high tsarki.
An rarraba Acetonitrile azaman ruwa mai ƙonewa (Kashi 2) tare da matsananciyar guba ta hanyar inhalation, shan fata, da kuma sha. Karɓa a cikin wuraren da ke da iska mai kyau tare da PPE masu dacewa (safofin hannu, tabarau, tufafi masu tsayayya da harshen wuta). Ajiye a cikin kwantena masu ƙarfi a ƙarƙashin iskar gas, nesa da tushen kunnawa, a +5 ° C zuwa + 30 ° C. Koma zuwa sabuwar SDS don cikakkun ƙa'idodin haɗari da zubarwa.
Menene lambar CAS don acetonitrile?
Lambar CAS ita ce 75-05-8.
Shin acetonitrile iri ɗaya ne da methyl cyanide?
Ee, acetonitrile (CH₃CN) ana kiransa methyl cyanide ko ethanenitrile.
Me yasa aka fi son acetonitrile akan methanol a cikin HPLC?
Acetonitrile yana ba da ƙananan danko, mafi kyawun ƙuduri mafi girma, gajeriyar lokutan gudu, da ƙananan matsa lamba a cikin tsarin jujjuyawar lokaci.
Wane mataki na acetonitrile ya fi dacewa ga LC-MS?
Matsayin LC-MS ko ultra-high tsarki acetonitrile tare da ƙarancin ions na ƙarfe, ruwa, da ƙazantattun kwayoyin halitta ana ba da shawarar don rage hayaniyar baya da ion.
Yaya ya kamata a adana acetonitrile?
Ajiye a wuri mai sanyi, busasshiyar wuri a cikin rufaffiyar kwantena a ƙarƙashin yanayi mara kyau don hana ɗaukar danshi da lalacewa.
Shin acetonitrile cikakke ne da ruwa?
Ee, acetonitrile gaba ɗaya ba shi da alaƙa da ruwa da yawancin kaushi na halitta.
Don ambato, takaddun bayanan fasaha, samfurori, ko oda mai yawa na acetonitrile CAS 75-05-8, da fatan za a tuntuɓi ƙungiyarmu.
