Benzo[b]thieno[3,2-d]thiophene-2-carbaldehyde CAS 31379-39-2

Description

Compared with other compounds in its class, the molecular weight of 218.29 g/mol gives Benzo[b]thieno[3,2-d]thiophene-2-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Benzo[b]thieno[3,2-d]thiophene-2-carbaldehyde (CAS 31379-39-2) is a high-purity analytical reference standard with the molecular formula C11H6OS2 and a molecular weight of 218.29 g/mol.

Benzo[b]thieno[3,2-d]thiophene-2-carbaldehyde (C11H6OS2) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
