Chemical Structure

5-Phenyl-2-thienylisocyanate CAS 321309-34-6 chemical structure

Description

Based on its molecular formula C11H7NOS, 5-Phenyl-2-thienylisocyanate contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

5-Phenyl-2-thienylisocyanate (CAS 321309-34-6) is a high-purity analytical reference standard with the molecular formula C11H7NOS and a molecular weight of 201.24 g/mol.

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.
