Chemical Structure

2,5-Diethynylthiophene CAS 79109-72-1 chemical structure

Description

CATO manufactures 2,5-Diethynylthiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2,5-Diethynylthiophene (CAS 79109-72-1) is a high-purity analytical reference standard with the molecular formula C8H4S and a molecular weight of 132.18 g/mol.

The molecular framework of 2,5-Diethynylthiophene (C8H4S) is characterized by sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

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