Chemical Structure
Description
4960-89-8 Bromo(~2~H_2_)methane DTXSID30584363 (CAS 4960-89-8), molecular formula CHD2Br and molecular weight 96.95 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, bromine substitution, 4960-89-8 Bromo(~2~H_2_)methane DTXSID30584363 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.95 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.
