Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 6-chloro-4-oxo-2-phenyl-1,4-dihydroquinoline-3-carboxylate (CAS 93663-74-2), molecular formula C18H14ClNO3 and molecular weight 327.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 6-chloro-4-oxo-2-phenyl-1,4-dihydroquinoline-3-carboxylate (C18H14ClNO3) is characterized by a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Ethyl 6-chloro-4-oxo-2-phenyl-1,4-dihydroquinoline-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
