Description

Structurally, 524684-52-4 A9C8MNF7CA Prinaberel [USAN:INN] 5-Benzoxazolol, 7-ethenyl-2-(3-fluoro-4-hydroxyphenyl)- ERB-041 ERB 041 Prinaberel 7-Ethenyl-2-(3-fluoro-4-hydroxyphenyl)benzoxazol-5-ol UNII-A9C8MNF7CA (C15H10FNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 271.24 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
