Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-{3-chloro-2-methylpyrazolo[1,5-a]pyrimidin-7-yl}pyridine (CAS 439097-29-7), a certified reference material (molecular formula C12H9ClN4, MW 244.68 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H9ClN4, 4-{3-chloro-2-methylpyrazolo[1,5-a]pyrimidin-7-yl}pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
