5-[(2-Hydroxyethyl)(methyl)amino]thiophene-2-carbaldehyde

“…In the title compound (I) ( Fig. 1), the S1-C4 bond length of 1.7398 (18) Å is longer than the corresponding S1-C15 bond length of 1.708 (2) Å in related thiophene derivative (Perašínová et al 2006), which is due to the fact that there is a higher π-electron delocalized system in the molecule 5-(fluoren-9-ylidenemethyl)thiophene-2-carbaldehyde. In the crystal structure of (I), the molecules are interconnected, via hydrogen bonds (Table 1)…”
