Chemical Structure
Description
The occurrence of 3-Bromo-1,1-dimethylcyclobutane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Bromo-1,1-dimethylcyclobutane (CAS 4237-75-6), a certified reference material (molecular formula C6H11Br, MW 163.06 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromo-1,1-dimethylcyclobutane (C6H11Br) is characterized by 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), 3-Bromo-1,1-dimethylcyclobutane 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.
