Chemical Structure

(E)-1,3-Dibromoprop-1-ene CAS 32121-07-6 chemical structure

Description

(E)-1,3-Dibromoprop-1-ene (CAS 32121-07-6), molecular formula C3H4Br2 and molecular weight 199.87 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3H4Br2, (E)-1,3-Dibromoprop-1-ene contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 199.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
