Tetrahydrofuran 99.9% THF HPLC

Our Tetrahydrofuran 99.9% waxay bixisaa joogtayn aan la mid ahayn falcelinta Grignard, chromatography, iyo polymer synthesis adduunka oo dhan. CAS 109-99-9 ether wareeg ah (THF, Oxolane, 1,4-Epoxybutane) waxay ku guulaysataa ≥99.9% nadiifinta GC oo leh ≤0.01% biyo iyo ≤0.001% peroxide — isku halaynta xubnahaaga iyo shaqada falanqeynta ayaa dalbanaya.

Maaddaama dareeraha ethereal ee ugu sarreeya, THF ay isku dheellitirto xalinta ugu fiican ee xeryahooda polar iyo kuwa aan dabaylaha ahayn ee leh isbeddel dhexdhexaad ah (bp 66°C) iyo aasaaska Lewis xooggan. Waxay u adeegtaa sida dareeraha doorashada ee Grignard iyo falcelinta organolithium, wejiga mobilada ee HPLC iyo GC ee falanqaynta dawooyinka, dhexdhexaadiyaha polymerization ee polytetramethylene ether glycol (PTMEG) iyo wax soo saarka PVC, iyo dareeraha falcelinta ee lithium aluminium yaraynta hydride-ka iyo isku-xidhka Suzuki. Qaab dhismeedka giraanta ee shanta xubnood ka kooban ayaa iska caabiya samaynta peroxide marka si habboon loo dejiyo.

Heerarka la heli karo: Heerka HPLC (UV-transparent, hadhaaga hoose), Anhydrous 99.9% (<50 ppm water), Peroxide-free stabilized (BHT ama butylated hydroxytoluene inhibitor), darajada reagent ACS, Heerka elektarooniga ah (biraha hoose, qayb-free).

Baakadaha: 180kg / DRUM durbaannada birta ah ee leh dahaarka u adkaysta; 1000L IBC kubado; Haamaha ISO (18MT) ee bulk. Nitrogen-madhan, uumiga-meel la geliyey, qashinka peroxide ee lagu daray fasalada xasilan.

Badbaadada & U Hogaansanaanta: Heerka 3 dareere guban kara (dhibcaha iftiinka -14°C); Fasalka 6.1 sunta neefsashada; khatarta peroxide ee soo-gaadhista hawada daba dheeraatay. GAARSIIN diiwaan gashan; TSCA ayaa ku taxan; IMDG/ADR shahaado. SDS dhamaystiran oo leh ka-hortagga dabka, borotokoolka baadhista peroxide, iyo hagida dib-u-celinta ka-hortagga. Taageerada farsamada ee maaraynta anhydrous, qalajinta shaandhada molecular, iyo maaraynta peroxide.

Supply: U dhoofinta tooska ah ee USA, Germany, Japan, China, India, South Korea, iyo 60+ suuqyada. COA buuxa oo leh qiimaha peroxide, ka kooban biyaha, iyo xooga saarista.

Codso qiimahaaga Tetrahydrofuran 99.9% 24 saacadood gudahood—qiimaha badan, shaybaarada heerka fuuq-baxa, iyo shahaado-la'aanta peroxide ee baahida.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.
