Chemical Structure

5-Ethoxy-3-methyl-1H-indole CAS 856070-85-4 chemical structure

Description

5-Ethoxy-3-methyl-1H-indole (CAS 856070-85-4) is a high-purity analytical reference standard with the molecular formula C11H13NO and a molecular weight of 175.23 g/mol.

The molecular framework of 5-Ethoxy-3-methyl-1H-indole (C11H13NO) 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.

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.

CATO manufactures 5-Ethoxy-3-methyl-1H-indole 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.
