2-Hydroxy-5-(methylthio)benzaldehyde (CAS 67868-84-2) is a high-purity analytical reference standard with the molecular formula C8H8O2S and a molecular weight of 168.21 g/mol.
The molecular framework of 2-Hydroxy-5-(methylthio)benzaldehyde (C8H8O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
