2-Aminonicotinic acid CAS 5345-47-1 yog ib qho tseem ceeb tshuaj thiab tshuaj tua kab nruab nrab. Kev lig kev cai, 3-nitrile pyridine lossis 3-amidopyridine yog siv los ua cov khoom siv raw, los ntawm kev ua kom lub nplhaib pyridine, chlorinating ntawm 2-txoj hauj lwm ntawm lub nplhaib pyridine thiab tom qab ntawd dhau los ntawm hydroxylation. Vim lub complex synthesis Circuit Court thiab tsis tshua muaj yield, tus nqi thiab tus nqi yog siab heev.
Ntseeg Tshuaj yog ib tug ua Tuam Tshoj 2-Aminonicotinic acid CAS 5345-47-1 chaw tsim tshuaj paus, tsum thiab exporter. Ua raws li kev ua raws li cov khoom lag luam zoo, kom peb cov 2-Aminonicotinic acid CAS 5345-47-1 tau txaus siab los ntawm ntau tus neeg siv khoom. Shandong Ntseeg
Peb zoo ntawm qhov zoo ntawm cov khoom siv tshuaj lom neeg hauv thaj chaw. Peb cov khoom raug xa tawm mus rau Tebchaws Europe, Tebchaws Meskas, Nyiv, Kaus Lim Qab Teb, Sab Hnub Tuaj Asia thiab lwm lub tebchaws thiab cheeb tsam. Nrog rau kev tshawb fawb thiab thev naus laus zis raws li kev qhia, kev ncaj ncees raws li lub hauv paus, zoo li lub neej, thiab tso siab rau lub tswv yim kev lag luam ntawm kev tsim kho tshiab thiab kev loj hlob, peb cia siab tias yuav tsim kev sib pauv thiab kev koom tes nrog cov neeg siv khoom hauv tsev thiab txawv teb chaws los tsim kev vam meej!
