Chemical Structure
Description
The occurrence of Ethyl 2-bromo-2-methylbutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-bromo-2-methylbutanoate (CAS 5398-71-0), molecular formula C7H13BrO2 and molecular weight 209.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-bromo-2-methylbutanoate (C7H13BrO2) 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.
As a certified reference material (CRM), Ethyl 2-bromo-2-methylbutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
