Chemical Structure
Description
The occurrence of 6-Bromo-3-cyclopropylpyrazolo[1,5-a]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Bromo-3-cyclopropylpyrazolo[1,5-a]pyrimidine (CAS 1379323-54-2), a certified reference material (molecular formula C9H8BrN3, MW 238.08 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H8BrN3, 6-Bromo-3-cyclopropylpyrazolo[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 238.08 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
