Description
CATO manufactures 2-Chloro-3-quinolinecarboxaldehyde 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.
CATO supplies 2-Chloro-3-quinolinecarboxaldehyde (CAS 73568-25-9), a certified reference material (molecular formula C10H6ClNO, MW 191.61 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H6ClNO, 2-Chloro-3-quinolinecarboxaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
