2-BROMO-7-IODO-5H-PYRROLO[2,3-B]PYRAZINE 2-BROMO-7-IODO-5H-PYRROLO[3,2-B]PYRAZINE 5-BROMO-3-IODO-1H-PYRROLO[2,3-B]PYRAZINE 5-BROMO-3-IODO-4,7-DIAZAINDOLE 757978-18-0 BC004027 (CAS 757978-18-0), molecular formula C7H12BrIN2 and molecular weight 330.99 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-BROMO-7-IODO-5H-PYRROLO[2,3-B]PYRAZINE 2-BROMO-7-IODO-5H-PYRROLO[3,2-B]PYRAZINE 5-BROMO-3-IODO-1H-PYRROLO[2,3-B]PYRAZINE 5-BROMO-3-IODO-4,7-DIAZAINDOLE 757978-18-0 BC004027 (C7H12BrIN2) contains a nitrile group, bromine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 330.99 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
