Iyini i-1,5-Naphthalenedisulfonic acid CAS 81-04-9?

Amakristalu amhlophe afana ne-1,5-Naphthalenedionic acid (ane-molecule amane amanzi e-crystal). Iphuzu lokuncibilika 240-245 ℃ (anhydrous). Incibilika emanzini nase-ethanol, ayincibiliki ku-ether. I-1,5-Naphthalenedionic acid isetshenziswa njengesihlanganisi samadayi. Isetshenziselwa ukukhiqiza izinto ezihlanganisa i-1,5-dihydroxynaphthalene nama-amino acid.
