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.
CATO supplies 4-bromo-3-methyl-1-phenyl-1H-pyrazol-5-amine hydrobromide (CAS 1955515-61-3), a certified reference material (molecular formula C10H10BrN3HBr, MW 333.03 g/mol) for analytical method development and quality control.
Structurally, 4-bromo-3-methyl-1-phenyl-1H-pyrazol-5-amine hydrobromide (C10H10BrN3HBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 333.03 g/mol, it falls into the moderately-high-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.
