Chemical Structure

1-Methyl-1H-indole-5-D CAS 1884330-89-5 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Methyl-1H-indole-5-D is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 131.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies 1-Methyl-1H-indole-5-D (CAS 1884330-89-5), a certified reference material (molecular formula C9H9N, MW 131.17 g/mol) for analytical method development and quality control.

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.
