Chemical Structure
Description
The occurrence of Ethyl 3-bromo-2,2-dimethylpropanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 3-bromo-2,2-dimethylpropanoate (CAS 2843-18-7), a certified reference material (molecular formula C7H13BrO2, MW 209.08 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 3-bromo-2,2-dimethylpropanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.08 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.
