Compared with other compounds in its class, the molecular weight of 157.19 g/mol gives 4-Methylthiazol-5-yl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Methylthiazol-5-yl acetate (CAS 256642-26-9), a certified reference material (molecular formula C6H7NO2S, MW 157.19 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methylthiazol-5-yl acetate (C6H7NO2S) is characterized by an amide group, 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 protonation state of its nitrogen-containing 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).
