Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 209.08 g/mol gives 5-(Bromomethyl)-2,2-dimethyl-1,3-dioxane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-(Bromomethyl)-2,2-dimethyl-1,3-dioxane (CAS 111934-94-2) is a high-purity analytical reference standard with the molecular formula C7H13BrO2 and a molecular weight of 209.08 g/mol.
5-(Bromomethyl)-2,2-dimethyl-1,3-dioxane (C7H13BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
