Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 169.45 g/mol gives 1-Bromo-2-(chloromethyl)cyclopropane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Bromo-2-(chloromethyl)cyclopropane (CAS 70650-32-7), a certified reference material (molecular formula C4H6BrCl, MW 169.45 g/mol) for analytical method development and quality control.
Structurally, 1-Bromo-2-(chloromethyl)cyclopropane (C4H6BrCl) contains chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 169.45 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.
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.
