Chemical Structure

3-Ethyl-3'-methyl-2,2'-bithiophene CAS 118168-85-7 chemical structure

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.

CATO supplies 3-Ethyl-3'-methyl-2,2'-bithiophene (CAS 118168-85-7), a certified reference material (molecular formula C11H12S2, MW 208.34 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, an aromatic ring system, 3-Ethyl-3'-methyl-2,2'-bithiophene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO manufactures 3-Ethyl-3'-methyl-2,2'-bithiophene 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.
