Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.29 g/mol gives 2-Keto molinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Keto molinate (CAS 24928-89-0), a certified reference material (molecular formula C9H15NO2S, MW 201.29 g/mol) for analytical method development and quality control.
2-Keto molinate (C9H15NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
