Chemical Structure
Description
CATO supplies 1-Bromo-3-methoxypropan-2-one (CAS 75522-04-2), a certified reference material (molecular formula C4H7BrO2, MW 167.00 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 1-Bromo-3-methoxypropan-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.00 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.
