Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-phenylpentanoic acid (CAS 1691861-88-7) is a high-purity analytical reference standard with the molecular formula C26H25NO4 and a molecular weight of 415.48 g/mol.
The molecular framework of 4-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-phenylpentanoic acid (C26H25NO4) 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).
As a certified reference material (CRM), 4-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-phenylpentanoic acid 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.
