573675-31-7 7-BROMO-4-CHLOROPYRIDO[3,2-D]PYRIMIDINE ABBYPHARMA AP-14-10972 BC003903 PYRIDO[3,2-D]PYRIMIDINE, 7-BROMO-4-CHLORO- (CAS 573675-31-7), molecular formula C7H13BrClN3 and molecular weight 254.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 573675-31-7 7-BROMO-4-CHLOROPYRIDO[3,2-D]PYRIMIDINE ABBYPHARMA AP-14-10972 BC003903 PYRIDO[3,2-D]PYRIMIDINE, 7-BROMO-4-CHLORO- (C7H13BrClN3) contains a nitrile group, chlorine/bromine 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 254.56 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
