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 Methyl 6-iodo-4-oxo-1,4-dihydroquinoline-2-carboxylate.
Methyl 6-iodo-4-oxo-1,4-dihydroquinoline-2-carboxylate (CAS 1176210-14-2), molecular formula C11H8INO3 and molecular weight 329.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 6-iodo-4-oxo-1,4-dihydroquinoline-2-carboxylate (C11H8INO3) 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 its high hydrophobicity (logP), 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.
