Chemical Structure
Description
The occurrence of 1-(Bromomethyl)-1-(difluoromethyl)cyclopropane is closely related to fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(Bromomethyl)-1-(difluoromethyl)cyclopropane (CAS 1314393-35-5), molecular formula C5H7BrF2 and molecular weight 185.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/bromine substitution, 1-(Bromomethyl)-1-(difluoromethyl)cyclopropane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.01 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.
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.
