Chemical Structure
Description
5-(Methylthio)-2-(trifluoromethyl)benzaldehyde (CAS 1288998-96-8) is a high-purity analytical reference standard with the molecular formula C9H7F3OS and a molecular weight of 220.21 g/mol.
Structurally, 5-(Methylthio)-2-(trifluoromethyl)benzaldehyde (C9H7F3OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 220.21 g/mol, it falls into the medium-molecular-weight range. 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).
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.
