Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, NM2KXJ990T 274925-86-9 Nebicapone [INN] Nebicapone Ethanone, 1-(3,4-dihydroxy-5-nitrophenyl)-2-phenyl- 1-(3,4-Dihydroxy-5-nitrophenyl)-2-phenylethan-1-one BIA 3-202 UNII-NM2KXJ990T is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
