Benzo[b]thieno[3,2-d]thiophene CAS 247-16-5

Description

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.

Benzo[b]thieno[3,2-d]thiophene (CAS 247-16-5) is a high-purity analytical reference standard with the molecular formula C10H6S2 and a molecular weight of 190.28 g/mol.

The molecular framework of Benzo[b]thieno[3,2-d]thiophene (C10H6S2) is characterized by sulfur-containing functionality, an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
