Hien ass bekannt fir seng Aarbechten iwwer Electrophil Substitutioun vum Naphtalin. D'Reegel vum Amstrong a Wynne seet datt een op enger Naphtalènedi -tri oder tretrasulfonescher Saier den nächsten (SO3H) net op de Positiounen ortho, para oder peri vun der éischter ka sëtzen. [Source?]
Den Armstrong war vun 1871 u Professer fir Chimie op der London Institution an duerno Assistent op der Uni London. Vun 1914 un huet hien als fräiberuffleche Cheemiker geschafft.
Vun 1875 bis 1893 war hie Sekretär vun der Chemical Society, 1894/95 da President an duerno Vizepresident. Vun 1876 u war hie Member vun der Royal Society.
Hien huet Verbindungen am Benzolmolekül ënnersicht an 1887 eng Formel verëffentlecht (Armstrong-Baeyersch Benzolformel). Donieft huet hie wichteg Aarbechten iwwer Terpene, Campher an hir Derivater verëffentlecht. Dës Weideren huet hie sech mat der Chimie vum Naphthalin beschäftegt wéi mat der Entwécklung vu syntheetesche Faarfstoffer.
