Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.13 g/mol gives Ethyl 2-bromoheptanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-bromoheptanoate (CAS 5333-88-0) is a high-purity analytical reference standard with the molecular formula C9H17BrO2 and a molecular weight of 237.13 g/mol.
The molecular framework of Ethyl 2-bromoheptanoate (C9H17BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 2-bromoheptanoate 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.
