Chemical Structure
Description
Structurally, 2-[4-(difluoromethyl)-3-methyl-6-oxo-1-phenyl-1h,6h,7h-pyrazolo[3,4-b]pyridin-7-yl]acetic acid (C16H13F2N3O3) 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 333.29 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).
