Chemical Structure

2-Ethyl-7-methyl-1H-indole CAS 91131-84-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 159.23 g/mol gives 2-Ethyl-7-methyl-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Ethyl-7-methyl-1H-indole (CAS 91131-84-9), a certified reference material (molecular formula C11H13N, MW 159.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-Ethyl-7-methyl-1H-indole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 159.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 2-Ethyl-7-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.
