Chemical Structure
Description
(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-acetamidophenyl)propanoic acid (CAS 1217801-44-9) is a high-purity analytical reference standard with the molecular formula C26H24N2O5 and a molecular weight of 444.48 g/mol.
The molecular framework of (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-acetamidophenyl)propanoic acid (C26H24N2O5) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-acetamidophenyl)propanoic 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.
