tert-Butyl 6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazole-1-carboxylate (CAS 1333319-72-4) is a high-purity analytical reference standard with the molecular formula C18H24BFN2O4 and a molecular weight of 362.20 g/mol.
Structurally, tert-Butyl 6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazole-1-carboxylate (C18H24BFN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 362.20 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
