 Seneciphylline (CAS NO.480-81-9) is also called 13,19-Didehydro-12-hydroxysenecionan-11,16-dione ; CCRIS 4336 ; HSDB 5188 ; Jacodine ; NCI-C61165 ; NSC 30622 ; Senecionan-11,16-dione, 13,19-didehydro-12-hydroxy- ; Seneciphyllin ; trans-15-Ethylidene-12beta-hydroxy-12alpha-methyl-13-methylenesenec-1-enine ; (1,6)Dioxacyclododecino(2,3,4-gh)pyrrolizine-2,7-dione, 3-ethylidene-3,4,5,6,9,11,13,14,14a,14b-decahydro-6-hydroxy-6-methyl-5-methylene-, (3Z,6R,14aR,14bR)- 13,19-Didehydro-12-hydroxysenecionan-11,16-dione ; Senecionan-11,16-dione, 13,19-didehydro-12-hydroxy- (9CI) . Seneciphylline (CAS NO.480-81-9) is white powder. It is stable, but reacts with oxygen in the air. Seneciphylline (CAS NO.480-81-9) is incompatible with alkali, oxidizing agents ans store under inert gas. It is insoluble in water. Flash point data are not available for Seneciphylline, but Seneciphylline is probably combustible.
