Description
CATO manufactures 7-Methoxy-2-thioxo-1,2-dihydroquinoline-3-carbaldehyde 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 7-Methoxy-2-thioxo-1,2-dihydroquinoline-3-carbaldehyde (CAS 880105-67-9), a certified reference material (molecular formula C11H9NO2S, MW 219.26 g/mol) for analytical method development and quality control.
The molecular framework of 7-Methoxy-2-thioxo-1,2-dihydroquinoline-3-carbaldehyde (C11H9NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
