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.
590-15-8 1-Propene, 1-bromo-, (E)- trans-1-Bromopropene (CAS 590-15-8), molecular formula C3H5Br and molecular weight 120.98 g/mol, is a CATO reference standard with documented purity and traceability.
590-15-8 1-Propene, 1-bromo-, (E)- trans-1-Bromopropene (C3H5Br) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 590-15-8 1-Propene, 1-bromo-, (E)- trans-1-Bromopropene 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.
