Chemical Structure
Description
Based on its molecular formula C32H30S2, 2-(4-Hexylphenyl)-5-(4-(5-phenylthiophen-2-yl)phenyl)thiophene contains sulfur-containing functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 478.71 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.
2-(4-Hexylphenyl)-5-(4-(5-phenylthiophen-2-yl)phenyl)thiophene (CAS 1172135-81-7), molecular formula C32H30S2 and molecular weight 478.71 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
