Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl N-[(2E)-2-{[(5-iodopyridin-2-yl)amino]methylidene}-3-oxobutanoyl]carbamate.
Ethyl N-[(2E)-2-{[(5-iodopyridin-2-yl)amino]methylidene}-3-oxobutanoyl]carbamate (CAS 338401-07-3) is a high-purity analytical reference standard with the molecular formula C13H14IN3O4 and a molecular weight of 403.17 g/mol.
The molecular framework of Ethyl N-[(2E)-2-{[(5-iodopyridin-2-yl)amino]methylidene}-3-oxobutanoyl]carbamate (C13H14IN3O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
