Description
Compared with other compounds in its class, the molecular weight of 388.37 g/mol gives Thalidomide-O-amido-C3-NH2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Thalidomide-O-amido-C3-NH2 (CAS 2022182-57-4), molecular formula C18H20N4O6 and molecular weight 388.37 g/mol, is a CATO reference standard with documented purity and traceability.
Thalidomide-O-amido-C3-NH2 (C18H20N4O6) contains a flavonoid core, 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.
