Description
Compared with other compounds in its class, the molecular weight of 174.26 g/mol gives 3-(m-Tolyl)thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(m-Tolyl)thiophene (CAS 16938-72-0) is a high-purity analytical reference standard with the molecular formula C11H10S and a molecular weight of 174.26 g/mol.
Based on its molecular formula C11H10S, 3-(m-Tolyl)thiophene contains sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 174.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 3-(m-Tolyl)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.
