Compared with other compounds in its class, the molecular weight of 234.31 g/mol gives (2-Methoxy-5-methylphenyl)(thiophen-2-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-Methoxy-5-methylphenyl)(thiophen-2-yl)methanol (CAS 944657-68-5) is a high-purity analytical reference standard with the molecular formula C13H14O2S and a molecular weight of 234.31 g/mol.
The molecular framework of (2-Methoxy-5-methylphenyl)(thiophen-2-yl)methanol (C13H14O2S) 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 its high hydrophobicity (logP), 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
