Chemical Structure
Description
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.
4-Amino-5-bromo-6-methylpyrimidine 7752-48-9 C5H6BrN3 W8411 (CAS 7752-48-9), molecular formula C5H6BrN3 and molecular weight 188.03 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Amino-5-bromo-6-methylpyrimidine 7752-48-9 C5H6BrN3 W8411 (C5H6BrN3) contains a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 188.03 g/mol, it falls into the medium-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.
