5-((2-hydroxyethyl)(methyl)amino)-thieno[3,2-b]thiophene-2-carbaldehyde is a functionalized fused thienothiophene containing an aldehyde and a hydroxyethyl-methylamino substituent.
Its primary value is as a small-molecule heteroaromatic intermediate for carbonyl chemistry and scaffold derivatization rather than peptide synthesis.

Application Scope in Heteroaromatic Synthesis
The aldehyde can participate in reductive amination, condensation, olefination and related carbonyl transformations, while the fused sulfur heteroaromatic core provides a rigid conjugated scaffold.
Dual Functionalization
The hydroxyethyl substituent adds a second derivatization handle and increases polarity relative to an unsubstituted thienothiophene aldehyde. Orthogonality between alcohol and aldehyde chemistry should be considered during route design.
Procurement and QC
Confirm CAS 2174014-81-2, C10H11NO2S2 and MW 241.32 g/mol. For aldehyde chemistry, oxidation/reduction state and chromatographic purity are important lot attributes.
Specify the downstream carbonyl transformation and purity requirement when requesting larger-scale material.
