The occurrence of 1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)(methyl)amino)-1H-pyrrole-2,5-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)(methyl)amino)-1H-pyrrole-2,5-dione (CAS 138949-16-3) is a high-purity analytical reference standard with the molecular formula C11H7ClF3N3O2 and a molecular weight of 305.64 g/mol.
Structurally, 1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)(methyl)amino)-1H-pyrrole-2,5-dione (C11H7ClF3N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 305.64 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
