Chemical Structure
Description
CATO supplies Methyl 5,7-dichloro-4-hydroxyquinoline-2-carboxylate (CAS 130613-19-3), a certified reference material (molecular formula C11H7Cl2NO3, MW 272.08 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5,7-dichloro-4-hydroxyquinoline-2-carboxylate (C11H7Cl2NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
