Chemical Structure
Description
2-(2-Bromoethyl)-2,5,5-trimethyl-1,3-dioxane (CAS 87842-52-2), molecular formula C9H17BrO2 and molecular weight 237.13 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Bromoethyl)-2,5,5-trimethyl-1,3-dioxane (C9H17BrO2) 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.
