Chemical Structure
Description
The molecular framework of 1-Methyl-2-(m-tolyloxy)-1H-indole-3-carbaldehyde (C17H15NO2) 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.
1-Methyl-2-(m-tolyloxy)-1H-indole-3-carbaldehyde (CAS 338416-84-5), molecular formula C17H15NO2 and molecular weight 265.31 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
