2-bromo-1-(3,5-ditert-butyl-4-hydroxy-phenyl)ethanone CAS 14386-64-2

Description

As a certified reference material (CRM), 2-bromo-1-(3,5-ditert-butyl-4-hydroxy-phenyl)ethanone 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-1-(3,5-ditert-butyl-4-hydroxy-phenyl)ethanone (CAS 14386-64-2), molecular formula C16H29BrO2 and molecular weight 333.30 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H29BrO2, 2-bromo-1-(3,5-ditert-butyl-4-hydroxy-phenyl)ethanone 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 333.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
