4-Formylbenzoic acid CAS 619-66-9 yog insoluble nyob rau hauv dej, soluble nyob rau hauv DMF, thiab yuav undergo esterification thiab aldol condensation nrog cawv. Nws yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, dav siv hauv tshuaj, tshuaj tua kab, txheej, kua siv lead ua raw cov ntaub ntawv, cov ntaub ntawv polymer thiab naj hoom raw khoom.
Ntseeg Tshuaj yog ib tug ua Tuam Tshoj 4-Formylbenzoic acid CAS 619-66-9 chaw tsim tshuaj paus, tsum thiab exporter. Ua raws li kev ua raws li cov khoom zoo tshaj plaws, kom peb cov 4-Formylbenzoic acid CAS 619-66-9 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!
