Compared with other compounds in its class, the molecular weight of 204.31 g/mol gives 3-(Bis(methylthio)methylene)pentane-2,4-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(Bis(methylthio)methylene)pentane-2,4-dione (CAS 15908-50-6), a certified reference material (molecular formula C8H12O2S2, MW 204.31 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Bis(methylthio)methylene)pentane-2,4-dione (C8H12O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
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.
