Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 217.49 g/mol gives 1-Bromo-3-chloro-2,2-dimethoxypropane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-3-chloro-2,2-dimethoxypropane (CAS 22089-54-9), molecular formula C5H10BrClO2 and molecular weight 217.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 1-Bromo-3-chloro-2,2-dimethoxypropane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.49 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
