Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-(3,4-Dihydroquinolin-1(2H)-yl)-2-oxoethyl)-2-methyl-1H-indole-3-carbaldehyde (CAS 431909-24-9), molecular formula C21H20N2O2 and molecular weight 332.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-(3,4-Dihydroquinolin-1(2H)-yl)-2-oxoethyl)-2-methyl-1H-indole-3-carbaldehyde (C21H20N2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 1-(2-(3,4-Dihydroquinolin-1(2H)-yl)-2-oxoethyl)-2-methyl-1H-indole-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.
