Chemical Structure
Description
Owing to a nitrile group, bromine substitution, an aromatic ring system, 10-bromo-3,4,5,6,11,12-hexaazatricyclo[7.3.0.0²,⁶]dodeca-1(9),2,4,7,10-pentaene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 10-bromo-3,4,5,6,11,12-hexaazatricyclo[7.3.0.0²,⁶]dodeca-1(9),2,4,7,10-pentaene (CAS 957759-83-0), a certified reference material (molecular formula C6H3BrN6, MW 239.03 g/mol) for analytical method development and quality control.
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.
