N-(1-Naphthyl)ethylene-diamine dihydrochloride 5gr (Merck)

N-(1-Naphthyl)ethylenediamine dihydrochloride banyak digunakan dalam analisis kuantitatif nitrat dan nitrit dalam sampel air dengan kolorimetri. Ini mudah mengalami reaksi penggandengan diazonium dengan adanya nitrit untuk menghasilkan senyawa azo berwarna kuat. Sampel yang mengandung ion nitrit pertama-tama dinetralkan dan kemudian direaksikan dengan asam klorida encer pada 0 - 5 °C untuk menghasilkan asam nitrat. Kemudian ditambahkan larutan sulfanilamida dan N-(1-naftil)etilenadiamina dihidroklorida dengan volume yang berlebih tetapi tetap.

Silahkan diorder, bisa eceran maupun Drum untuk praktikum sekolah, Universitas, Lembaga/instansi dll.
