2019 Isimbo esitsha esiPhezulu seThengiso 2, 5-Dimethoxybenzaldehyde CAS 93-02-7, CAS 102-97-6

Abasebenzi bethu basoloko bekumoya “wophuculo oluqhubekayo kunye nokugqwesa”, kunye neemveliso ezikumgangatho ophezulu, ixabiso elincomekayo kunye neenkonzo ezilungileyo emva kokuthengisa, sizama ukuphumelela intembeko yomthengi ngamnye ngo-2019 iSitayile esitsha sokuThengisa.2, 5-Dimethoxybenzaldehyde CAS 93-02-7, I-CAS 102-97-6, Sinokwenza iimpahla ngokweemfuno zakho kwaye siya kukupakisha ngokwakho xa ufumana.
Abasebenzi bethu basoloko benomoya “wophuculo oluqhubekayo nokugqwesa”, kunye neemveliso ezikumgangatho ophezulu, ixabiso elincomekayo kunye neenkonzo ezilungileyo emva kokuthengisa, sizama ukuphumelela intembeko yomthengi ngamnye, Ngendibano yocweyo ephucukileyo, iqela loyilo eliqeqeshiweyo kunye nenkqubo engqongqo yolawulo lomgangatho, esekwe kumbindi ukuya kwisiphelo esiphezulu esiphawulwe njengendawo yokuthengisa, iimpahla zethu zezentengiso zethu zaseYurophu kwaye zithengisa ngokukhawuleza kwintengiso yaseMelika kunye ne-QR. kunye noYisilanya.

I-2,5-i-Dimethoxybenzaldehyde yi-crystalline powder ekhanyayo kunye ne-molecular weight ye-166.18 kunye neqondo lokubilisa le-146 ° C. Iyanyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-ether. Isetyenziswa ikakhulu njenge pharmaceutical intermediate.

Ukongeza kwi-oxidized okanye ukunciphisa i-2,5-dimethoxybenzoic acid, i-benzonitrile okanye i-benzyl alcohol,I-2,5-dimethoxybenzaldehydeyona ngokwayo inexabiso elilodwa lesicelo. Ngokuphendula ngezinto ezineentlobo ezahlukeneyo zamaqela asebenzayo, iimolekyuli zamachiza ezinezakhiwo ezahlukeneyo kunye nemiphumo eyahlukeneyo inokufumaneka. Isifo sikaParkinson (PD) sisifo esiqhelekileyo se-neurodeergenerative, kwaye iimpawu zaso eziphambili zeklinikhi ziquka ukungcangcazela kwemisipha, ukuqina, ubunzima bokuhamba, ukuma komzimba kunye nokuphazamiseka kokuhamba kakuhle. Uphuhliso olongezelelweyo luya kukhokelela ekuqaphelisweni, ukuqonda, ukuphazamiseka kwememori kunye nesifo sengqondo esicacileyo. Okwangoku, unyango lwePD ikakhulu lubandakanya unyango lweziyobisi, unyango lotyando kunye nonyango lwemfuza. Kunyango lweziyobisi, i-phenamidine ifunyenwe ibe nefuthe elihle kwi-PD, enetyhefu ephantsi kunye nokhuseleko oluhle, kwaye i-synthesis ye-phenamidine idinga ukusetyenziswa kwe-2,5-dimethoxybenzaldehyde njengento yokuqala.

Ngokwendlela yokudibanisa echazwe kuncwadi,I-2,5-dimethoxybenzaldehydeifunyenwe ikakhulu ngokusabela kwi-1,4-dimethoxybenzene kunye ne-agent ye-formylation. I-Formylation agents ziquka (1) umxube we-1,1-dichloromethyl ether kunye ne-titanium tetrachloride; (2) umxube we-N, N-dimethylformamide kunye ne-phosphorus oxychloride, umxube we-N, N-dimethylformamide kunye ne-oxalyl chloride; (3) umxube we-N, N-dimethylformamide kunye ne-thionyl chloride okanye umxube we-urotropine kunye ne-magnesium chloride. Nangona kunjalo, ezi ndlela zifuna ukusetyenziswa kwesixa esikhulu se-titanium tetrachloride, i-phosphorus oxychloride okanye i-thionyl chloride. Ezi reagents aziqinisekanga kwaye zibole ngokulula, kwaye isixa esikhulu segesi ye-hydrochloric acid ikhutshwa ngexesha lokuphendula, elingenabume bendalo kwaye lineemfuno eziphezulu zenkqubo yokusebenza.

Kuye kwacetywa indlela entsha yokudibanisa. Le ndlela isebenzisa i-1,4-dimethoxybenzene kunye ne-formaldehyde njengezinto eziluhlaza, kwaye yenza i-photooxidative coupling reaction phambi kwe-oksijini kunye ne-catalyst phantsi kwe-irradiation yokukhanya okuluhlaza okwesibhakabhaka ukwenza ngokufanelekileyo i-2,5-dimethoxybenzaldehyde. Le ndlela isebenzisa ioksijini okanye umoya njenge-oxidant, ayivelisi igesi eneasidi, kwaye ihambelana nokusingqongileyo. Ukongeza, le ndlela isebenzisa i-cobalt encinci njenge-catalyst, ephantsi kwexabiso kwaye ifanele ukusetyenziswa kwezoshishino.
