Chemical Structure
Description
Ethyl 8-bromo-2-methyloctanoate (CAS 73828-69-0), molecular formula C11H21BrO2 and molecular weight 265.19 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H21BrO2, Ethyl 8-bromo-2-methyloctanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 265.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 8-bromo-2-methyloctanoate 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.
