Chemical Structure
Description
7-bromo-5H-pyrrolo[3,2-d]pyrimidine (CAS 1378816-68-2), molecular formula C6H12BrN3 and molecular weight 206.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H12BrN3, 7-bromo-5H-pyrrolo[3,2-d]pyrimidine contains a nitrile group, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 206.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
