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.
3-(p-Tolyl)thiophene (CAS 16939-05-2) 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-(p-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.
CATO manufactures 3-(p-Tolyl)thiophene 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.
