Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 329.78 g/mol gives Ethyl 7-(benzyloxy)-5-chloro-1H-indole-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 7-(benzyloxy)-5-chloro-1H-indole-2-carboxylate (CAS 1956386-42-7), a certified reference material (molecular formula C18H16ClNO3, MW 329.78 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 7-(benzyloxy)-5-chloro-1H-indole-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.78 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 Ethyl 7-(benzyloxy)-5-chloro-1H-indole-2-carboxylate 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.
