Chemical Structure
Description
CATO supplies Ethyl 6-fluoro-4-hydroxy-8-iodoquinoline-3-carboxylate (CAS 1171925-75-9), a certified reference material (molecular formula C12H9FINO3, MW 361.11 g/mol) for analytical method development and quality control.
Structurally, Ethyl 6-fluoro-4-hydroxy-8-iodoquinoline-3-carboxylate (C12H9FINO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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 361.11 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
CATO manufactures Ethyl 6-fluoro-4-hydroxy-8-iodoquinoline-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
