1-Naphthol is a forerunner to a array of
insecticides including carbaryl and pharmaceuticals including nadolol. It
undergoes azo coupling to accord assorted azo dyes, but these are about beneath
advantageous than those acquired from 2-naphthol.
In Molisch's test, 1-naphthol attenuated in
ethanol, accepted as Molisch's reagent, is acclimated as reagent for audition
the attendance of carbohydrates. The analysis accepted as Molisch's analysis
would accord a red- or purple-colored admixture to announce the attendance of
carbohydrate. The accelerated furfural test, agnate to Molisch's test, aswell
uses 1-naphthol.
The Sakaguchi analysis uses 1-naphthol with
sodium hypobromite to ascertain the attendance of arginine in proteins.
The Voges–Proskauer analysis uses
1-naphthol in potassium hydroxide (KOH) band-aid to ascertain the breakdown of
glucose into acetoin which is acclimated by bacilli for alien activity storage.
A absolute analysis will be adumbrated by the actualization of a red blush of
the aboriginal chicken solution.
