ʻO ka waikawa Naphalene-2-sulfonic kahi mea hoʻohuihui kemika koʻikoʻi i hoʻohana nui ʻia i nā ʻoihana dye, textile, a me ka ʻili. Hoʻohana ʻia no ka hana ʻana i nā mea hoʻohuihui dye e like me 2-naphthol, 2-naphthol sulfonic acid, 1,3,6-naphthalene trisulfonic acid, 2-naphthylamine sulfonic acid, etc. Dehydrogenation catalyst. ʻO ka hana ʻana me ka formaldehyde hiki ke hana i ka diffusion agent N (diffusion agent NNO). Hoʻohana ʻia ka waikawa Naphthalene-2-sulfonic ma ke ʻano he reagent biochemical a me ka reagent hoʻokolohua no ka hoʻoholo ʻana o ka peptone a me ka protein.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
