The occurrence of Bromo-PEG2-MS is closely related to a carbohydrate-derived structure, a sulfone group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Bromo-PEG2-MS (CAS 1935075-34-5), a certified reference material (molecular formula C5H11BrO4S, MW 247.11 g/mol) for analytical method development and quality control.
Structurally, Bromo-PEG2-MS (C5H11BrO4S) contains a carbohydrate-derived structure, a sulfone group, 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 247.11 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), Bromo-PEG2-MS 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.
