Chemical Structure
Description
Vinyl-<SUP>13</SUP>C<SUB>2</SUB> bromide (CAS 101391-57-5), molecular formula [13C]2H3Br and molecular weight 108.93 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, Vinyl-<SUP>13</SUP>C<SUB>2</SUB> bromide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.93 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.
