CATO supplies (4S,4′S)-2,2′-(5-Nitro-1,3-phenylene)bis[4,5-dihydro-4-(phenylmethyl)oxazole] (CAS 926625-38-9), a certified reference material (molecular formula C26H23N3O4, MW 441.48 g/mol) for analytical method development and quality control.
The molecular framework of (4S,4′S)-2,2′-(5-Nitro-1,3-phenylene)bis[4,5-dihydro-4-(phenylmethyl)oxazole] (C26H23N3O4) is characterized by a steroid core, an amide 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
