(9H-fluoren-9-yl)methyl (S)-(1-(4-(tert-butoxy)phenyl)-3-hydroxypropan-2-yl)carbamate (CAS 187526-99-4) is a high-purity analytical reference standard with the molecular formula C28H31NO4 and a molecular weight of 445.55 g/mol.
The molecular framework of (9H-fluoren-9-yl)methyl (S)-(1-(4-(tert-butoxy)phenyl)-3-hydroxypropan-2-yl)carbamate (C28H31NO4) 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.
