Description
CATO manufactures 4-Chloro-6-iodo-3-nitroquinoline 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.
4-Chloro-6-iodo-3-nitroquinoline (CAS 1345447-25-7), molecular formula C9H4ClIN2O2 and molecular weight 334.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-6-iodo-3-nitroquinoline (C9H4ClIN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/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. 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.
