Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.26 g/mol gives 2-Phenylisoxazolidine-3,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Phenylisoxazolidine-3,5-dione (CAS 5305-00-0), molecular formula C8H13NO5S and molecular weight 235.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Phenylisoxazolidine-3,5-dione (C8H13NO5S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. 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.
