Description
CATO supplies 23C21BW281 7789-67-5 Stannic bromide Stannane, tetrabromo- Tin tetrabromide Tin(IV) bromide (1:4) EINECS 232-184-5 Tin perbromide UNII-23C21BW281 (CAS 7789-67-5), a certified reference material (molecular formula Br4Sn, MW 438.33 g/mol) for analytical method development and quality control.
Owing to bromine substitution, 23C21BW281 7789-67-5 Stannic bromide Stannane, tetrabromo- Tin tetrabromide Tin(IV) bromide (1:4) EINECS 232-184-5 Tin perbromide UNII-23C21BW281 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 438.33 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.
