Product name:N-(1-naphthyl) ethylenediamine dihydrochloride
CAS: 1465-25-4
Molecular Formula: C12H14N2·2HCl
Molecular Weight: 259.20
Product description:Special reagent is used for monitoring of nitrogen dioxide in the atmosphere. Nitrogen dioxide in the air is absorbed by the liquid nitrogen dioxide absorption and diazotization reaction generated pink azo dye. Generated azo dye the strongest and ultraviolet-visible absorption wavelength of 540 nm absorbance proportional to the content of absorbed nitrogen dioxide.Environmental protection reagent, hydrochloric acid naphthalene ethylenediamine colorimetric method determination of nitrogen oxides in the atmosphere on the determination of aniline, chemicals and determination of sulfur ammonia and nitrite, can also be spectrometric amino phenol, phenylenediamine, 2 nitroaniline, chloroaniline, mercaptan and ammonia sulfonyl, etc.
