Chemical Structure
Description
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.
1-[3-(bromomethyl)-1-bicyclo[1.1.1]pentanyl]ethanone (CAS 2306268-76-6), molecular formula C8H11BrO and molecular weight 203.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[3-(bromomethyl)-1-bicyclo[1.1.1]pentanyl]ethanone (C8H11BrO) is characterized by 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.
As a certified reference material (CRM), 1-[3-(bromomethyl)-1-bicyclo[1.1.1]pentanyl]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.
