Chemical Structure

1,3,5-Tri(thiophen-2-yl)benzene CAS 15509-95-2 chemical structure

Description

As a certified reference material (CRM), 1,3,5-Tri(thiophen-2-yl)benzene 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.

1,3,5-Tri(thiophen-2-yl)benzene (CAS 15509-95-2) is a high-purity analytical reference standard with the molecular formula C18H12S3 and a molecular weight of 324.48 g/mol.

Based on its molecular formula C18H12S3, 1,3,5-Tri(thiophen-2-yl)benzene contains sulfur-containing functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.48 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.

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.
