4-Bromo-6-ethoxypyrazolo[1,5-a]pyridine-3-carbonitrile CAS 2222653-69-0

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-6-ethoxypyrazolo[1,5-a]pyridine-3-carbonitrile.

4-Bromo-6-ethoxypyrazolo[1,5-a]pyridine-3-carbonitrile (CAS 2222653-69-0) is a high-purity analytical reference standard with the molecular formula C10H8BrN3O and a molecular weight of 266.09 g/mol.

Based on its molecular formula C10H8BrN3O, 4-Bromo-6-ethoxypyrazolo[1,5-a]pyridine-3-carbonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.09 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.
