He aha ka 1,5-Naphthalenedisulfonic acid CAS 81-04-9?

ʻO 1,5-Naphthalenedionic acid nā kristal keʻokeʻo e like me ka papa (me ʻehā mau molekala o ka wai kristal). Hehi 240-245 ℃ (anhydrous). Hoʻoheheʻe ʻia i ka wai a me ka ethanol, hoʻoheheʻe ʻole ʻia i ka ether. Hoʻohana ʻia ka 1,5-Naphthalenedionic acid ma ke ʻano he waena no nā kala. Hoʻohana ʻia no ka hana ʻana o nā waena e like me 1,5-dihydroxynaphthalene a me nā waikawa amino.
