Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-2-ethyl-3-methylbutanoyl chloride 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.
2-Bromo-2-ethyl-3-methylbutanoyl chloride (CAS 854871-19-5), molecular formula C7H12BrClO and molecular weight 227.53 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-2-ethyl-3-methylbutanoyl chloride (C7H12BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
