Use	organic synthesis.
production method	from 1-naphthol and aniline as raw materials. First, 1-naphthol and sodium hydroxide solution were reacted to prepare 1-naphthol sodium solution; Aniline and sodium nitrite were reacted to prepare diazonium salt solution. Both were reacted at 10 ° C. Or lower to obtain 4-phenylazo -1-naphthol. This is then reduced to form a salt with hydrochloric acid to give 4-amino-1-naphthol hydrochloride.
