Chemical Structure
Description
As a certified reference material (CRM), 4-((2-(4-Nitrophenoxy)ethyl)amino)butanoic 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.
4-((2-(4-Nitrophenoxy)ethyl)amino)butanoic acid (CAS 1245698-26-3) is a high-purity analytical reference standard with the molecular formula C12H16N2O5 and a molecular weight of 268.27 g/mol.
The molecular framework of 4-((2-(4-Nitrophenoxy)ethyl)amino)butanoic acid (C12H16N2O5) is characterized by an amino-acid-derived structure, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
