Chemical Structure
Description
The occurrence of 5-((5-Chloropyridin-2-yl)amino)-5-oxopentanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-((5-Chloropyridin-2-yl)amino)-5-oxopentanoic acid (CAS 4121-54-4) is a high-purity analytical reference standard with the molecular formula C10H11ClN2O3 and a molecular weight of 242.66 g/mol.
The molecular framework of 5-((5-Chloropyridin-2-yl)amino)-5-oxopentanoic acid (C10H11ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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), 5-((5-Chloropyridin-2-yl)amino)-5-oxopentanoic 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.
