Chemical Structure

3-Undecylthieno[3,2-b]thiophene CAS 950223-97-9 chemical structure

Description

As a certified reference material (CRM), 3-Undecylthieno[3,2-b]thiophene 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.

3-Undecylthieno[3,2-b]thiophene (CAS 950223-97-9), molecular formula C17H26S2 and molecular weight 294.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Undecylthieno[3,2-b]thiophene (C17H26S2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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