3,3'-Dihexyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde CAS 170702-08-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,3'-Dihexyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde (CAS 170702-08-6) is a high-purity analytical reference standard with the molecular formula C22H30O2S2 and a molecular weight of 390.60 g/mol.

The molecular framework of 3,3'-Dihexyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde (C22H30O2S2) is characterized by a steroid core, 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 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).

As a certified reference material (CRM), 3,3'-Dihexyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
