Chemical Structure
Description
The molecular framework of 1-Ethyl-5-methoxy-2-methyl-1H-indole-3-carbaldehyde (C13H15NO2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
1-Ethyl-5-methoxy-2-methyl-1H-indole-3-carbaldehyde (CAS 36149-66-3) is a high-purity analytical reference standard with the molecular formula C13H15NO2 and a molecular weight of 217.26 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
