Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.11 g/mol gives Ethyl 4-Bromoindole-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-Bromoindole-2-carboxylate (CAS 103858-52-2), molecular formula C11H10BrNO2 and molecular weight 268.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 4-Bromoindole-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.11 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 4-Bromoindole-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.
