Chemical Structure
Description
The occurrence of 73568-43-1 7-Chloro-2-oxo-1,2-dihydroquinoline-3-carbaldehyde DTXSID30501116 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
73568-43-1 7-Chloro-2-oxo-1,2-dihydroquinoline-3-carbaldehyde DTXSID30501116 (CAS 73568-43-1), molecular formula C10H16ClNO2 and molecular weight 217.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 73568-43-1 7-Chloro-2-oxo-1,2-dihydroquinoline-3-carbaldehyde DTXSID30501116 (C10H16ClNO2) is characterized by an amide group, a carboxylic acid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 73568-43-1 7-Chloro-2-oxo-1,2-dihydroquinoline-3-carbaldehyde DTXSID30501116 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.
