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

I-4,6-Dihydroxyisophthalic acid yi-organic compound, eyaziwa ngokuba yi-terephthalic acid (TDA). I-white crystalline powder, i-soluble emanzini, i-alcohol kunye ne-ester solvents, kwaye i-insoluble kwi-solvents non-polar. I-4,6-Dihydroxyisophthalic acid i-asidi ebuthakathaka, kunye neqela layo le-hydroxyl li-acidic, elinokuthi lithathe inxaxheba kwi-esterification kunye ne-acylation reactions.
