Chemical Structure

2-Ethyl-5-methylthiophene CAS 40323-88-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 126.22 g/mol gives 2-Ethyl-5-methylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Ethyl-5-methylthiophene (CAS 40323-88-4) is a high-purity analytical reference standard with the molecular formula C7H10S and a molecular weight of 126.22 g/mol.

The molecular framework of 2-Ethyl-5-methylthiophene (C7H10S) is characterized by sulfur-containing functionality. 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.

CATO manufactures 2-Ethyl-5-methylthiophene 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.
