Chemical Structure
Description
Ethyl 3-iodo-2-methyl-4-oxo-1,4-dihydroquinoline-6-carboxylate (CAS 1330755-92-4), molecular formula C13H12INO3 and molecular weight 357.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 3-iodo-2-methyl-4-oxo-1,4-dihydroquinoline-6-carboxylate (C13H12INO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 357.14 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
