Description
CATO supplies 4-Bromo-1,2-dichlorobutane (CAS 26204-05-7), a certified reference material (molecular formula C4H7BrCl2, MW 205.91 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-1,2-dichlorobutane (C4H7BrCl2) contains chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 205.91 g/mol, it falls into the medium-molecular-weight range. 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), 4-Bromo-1,2-dichlorobutane 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.
