Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.12 g/mol gives Ethyl 3-bromo-5-ethylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 3-bromo-5-ethylbenzoate (CAS 272130-62-8), a certified reference material (molecular formula C11H13BrO2, MW 257.12 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 3-bromo-5-ethylbenzoate (C11H13BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-bromo-5-ethylbenzoate 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.
