Iithegi zeMveliso

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

Iikristale ezimhlophe ezifana ne-1,5-Naphthalenedionic acid (ezineemolekyuli ezine zamanzi ekristale). Iqondo lokunyibilika yi-240-245 ℃ (i-anhydrous). Inyibilika emanzini nakwi-ethanol, ayinyibiliki kwi-ether. I-1,5-Naphthalenedionic acid isetyenziswa njenge-intermediate yeedayi. Isetyenziselwa ukuvelisa izinto eziphakathi ezifana ne-1,5-dihydroxynaphthalene kunye nee-amino acids.
