Chemical Structure
Description
As a certified reference material (CRM), 7-(4-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)butanamido)heptanoic 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.
7-(4-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)butanamido)heptanoic acid (CAS 2172142-06-0) is a high-purity analytical reference standard with the molecular formula C26H32N2O5 and a molecular weight of 452.54 g/mol.
The molecular framework of 7-(4-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)butanamido)heptanoic acid (C26H32N2O5) 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).
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.
