Chemical Structure

[(E)-2-bromoethenyl]cyclopropane CAS 220132-80-9 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

[(E)-2-bromoethenyl]cyclopropane (CAS 220132-80-9), molecular formula C5H7Br and molecular weight 147.01 g/mol, is a CATO reference standard with documented purity and traceability.

[(E)-2-bromoethenyl]cyclopropane (C5H7Br) 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.

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.
