Iyini i-4,6-DIHYDROXYISOPHTHALIC ACID CAS 19829-74-4 ?

I-4,6-Dihydroxyisophthalic acid iyinhlanganisela ephilayo, eyaziwa nangokuthi i-terephthalic acid (TDA). Kuyimpushana emhlophe ecwebezelayo, encibilika emanzini, etshwaleni nasezincibilikisini ze-ester, futhi ayincibiliki ezincibilikisini ezingezona ze-polar. I-4,6-Dihydroxyisophthalic acid iyi-asidi ebuthakathaka, futhi iqembu layo le-hydroxyl li-acidic, elingabamba iqhaza ekuphenduleni kwe-esterification kanye ne-acylation.
