Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 87.08 g/mol gives Isoxazolidin-3-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isoxazolidin-3-one (CAS 1192-07-0), molecular formula C3H5NO2 and molecular weight 87.08 g/mol, is a CATO reference standard with documented purity and traceability.
Isoxazolidin-3-one (C3H5NO2) contains an amino-acid-derived structure, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
