Chemical Structure
Description
The occurrence of 5-Chloro-3-ethyl-3-methyl-3H-indole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-3-ethyl-3-methyl-3H-indole (CAS 923037-18-7), a certified reference material (molecular formula C11H12ClN, MW 193.67 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-Chloro-3-ethyl-3-methyl-3H-indole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 193.67 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.
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 5-Chloro-3-ethyl-3-methyl-3H-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.
