9,10-Dihydro-4H-benzo(4,5)cyclohepta(1,2-b)thiophen-4-one CAS 1622-55-5

Description

The occurrence of 9,10-Dihydro-4H-benzo(4,5)cyclohepta(1,2-b)thiophen-4-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

9,10-Dihydro-4H-benzo(4,5)cyclohepta(1,2-b)thiophen-4-one (CAS 1622-55-5), molecular formula C13H10OS and molecular weight 214.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H10OS, 9,10-Dihydro-4H-benzo(4,5)cyclohepta(1,2-b)thiophen-4-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.28 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.
