Kugwiritsa ntchito

Naphalene-2-sulfonic acid ndi mankhwala ofunikira kwambiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale opanga utoto, nsalu, ndi zikopa. Amagwiritsidwa ntchito popanga zinthu zopaka utoto monga 2-naphthol, 2-naphthol sulfonic acid, 1,3,6-naphthalene trisulfonic acid, 2-naphthylamine sulfonic acid, ndi zina zotero. Chothandizira kuchotsa hydrogenation. Kuyanjana ndi formaldehyde kumatha kupanga N (diffusion agent NNO). Naphthalene-2-sulfonic acid imagwiritsidwanso ntchito ngati reagent ya biochemical komanso reagent yoyesera kuti mudziwe peptone ndi mapuloteni.
