Description
CATO supplies 3-Butyl-1-methyl-1H-imidazol-3-ium (2S,3S)-3-carboxy-2,3-dihydroxypropanoate (CAS 1418280-68-8), a certified reference material (molecular formula C4H5O6C8H15N2, MW 288.30 g/mol) for analytical method development and quality control.
3-Butyl-1-methyl-1H-imidazol-3-ium (2S,3S)-3-carboxy-2,3-dihydroxypropanoate (C4H5O6C8H15N2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
