Chemical Structure

3-Bromo-5-methyl-7-propyl-pyrazolo[1,5-a]pyrimidine CAS 43024-41-5 chemical structure

Description

CATO supplies 3-Bromo-5-methyl-7-propyl-pyrazolo[1,5-a]pyrimidine (CAS 43024-41-5), a certified reference material (molecular formula C10H12BrN3, MW 254.13 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H12BrN3, 3-Bromo-5-methyl-7-propyl-pyrazolo[1,5-a]pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
