Chemical Structure
Description
As a certified reference material (CRM), (9H-fluoren-9-yl)methyl (S)-(1-hydroxy-4-phenylbutan-2-yl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(9H-fluoren-9-yl)methyl (S)-(1-hydroxy-4-phenylbutan-2-yl)carbamate (CAS 1139710-66-9) is a high-purity analytical reference standard with the molecular formula C25H25NO3 and a molecular weight of 387.47 g/mol.
Structurally, (9H-fluoren-9-yl)methyl (S)-(1-hydroxy-4-phenylbutan-2-yl)carbamate (C25H25NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 387.47 g/mol, it falls into the moderately-high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
