Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.08 g/mol gives 3-bromopyrazolo[1,5-a]pyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-bromopyrazolo[1,5-a]pyrazine (CAS 53902-93-5), a certified reference material (molecular formula C6H12BrN3, MW 206.08 g/mol) for analytical method development and quality control.
The molecular framework of 3-bromopyrazolo[1,5-a]pyrazine (C6H12BrN3) is characterized by a nitrile group, 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.
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.
