Compared with other compounds in its class, the molecular weight of 168.26 g/mol gives 2-Butyryl-3-methylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Butyryl-3-methylthiophene (CAS 197236-32-1), a certified reference material (molecular formula C9H12OS, MW 168.26 g/mol) for analytical method development and quality control.
The molecular framework of 2-Butyryl-3-methylthiophene (C9H12OS) is characterized by sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
