Chemical Structure

2-Ethyl-3-methyl-1H-indol-7-ol CAS 25158-25-2 chemical structure

Description

CATO supplies 2-Ethyl-3-methyl-1H-indol-7-ol (CAS 25158-25-2), a certified reference material (molecular formula C11H13NO, MW 175.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Ethyl-3-methyl-1H-indol-7-ol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 175.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
