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.
1,1-Dibromo-2,2-bis(chloromethyl)cyclopropane (CAS 98577-44-7) is a high-purity analytical reference standard with the molecular formula C5H6Br2Cl2 and a molecular weight of 296.82 g/mol.
Owing to chlorine/bromine substitution, 1,1-Dibromo-2,2-bis(chloromethyl)cyclopropane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
