Chemical Structure
Description
The molecular framework of 5,5'-(Benzo[c][1,2,5]thiadiazole-4,7-diyl)bis(thiophene-2-carbaldehyde) (C16H8N2O2S3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
