4-Chloro-2-(furan-2-yl)pyrazolo[1,5-a]pyrazine CAS 1713461-97-2 chemical structure

Description

The occurrence of 4-Chloro-2-(furan-2-yl)pyrazolo[1,5-a]pyrazine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-2-(furan-2-yl)pyrazolo[1,5-a]pyrazine (CAS 1713461-97-2), molecular formula C10H6ClN3O and molecular weight 219.63 g/mol, is a CATO reference standard with documented purity and traceability.

4-Chloro-2-(furan-2-yl)pyrazolo[1,5-a]pyrazine (C10H6ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
