Piperazine
The first link does not mention "Diphenazin" The second link returns an error. Please verify your sources? https://patents.google.com/patent/DE1041501B/en?oq=DE1041501+ does not mention "Diphenazin" either. Cheers Adakiko (talk) 11:28, 13 July 2022 (UTC)
 * Thanks for fixing the second link. Why not reference the PubChem source? English-language sources are preferred. See WP:NONENG. Cheers Adakiko (talk) 11:57, 13 July 2022 (UTC)
