Chemical Structure
Description
Ethyl 4-(7-hydroxy-2,2,4-trimethyl-3,4-dihydroquinolin-1(2H)-yl)butanoate (CAS 1448822-28-3), molecular formula C18H27NO3 and molecular weight 305.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 4-(7-hydroxy-2,2,4-trimethyl-3,4-dihydroquinolin-1(2H)-yl)butanoate (C18H27NO3) is characterized by a steroid core, an amide 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. 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.
CATO manufactures Ethyl 4-(7-hydroxy-2,2,4-trimethyl-3,4-dihydroquinolin-1(2H)-yl)butanoate 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.
