Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-1-(1-methoxypropan-2-yl)-1h-pyrazol-3-amine.
4-Bromo-1-(1-methoxypropan-2-yl)-1h-pyrazol-3-amine (CAS 1339229-90-1) is a high-purity analytical reference standard with the molecular formula C7H12BrN3O and a molecular weight of 234.09 g/mol.
The molecular framework of 4-Bromo-1-(1-methoxypropan-2-yl)-1h-pyrazol-3-amine (C7H12BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
