1-(2-(4-Chlorophenyl)-7-methylpyrazolo[1,5-a]pyrimidin-6-yl)ethan-1-one CAS 175201-63-5

Description

Compared with other compounds in its class, the molecular weight of 285.73 g/mol gives 1-(2-(4-Chlorophenyl)-7-methylpyrazolo[1,5-a]pyrimidin-6-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-(4-Chlorophenyl)-7-methylpyrazolo[1,5-a]pyrimidin-6-yl)ethan-1-one (CAS 175201-63-5), molecular formula C15H12ClN3O and molecular weight 285.73 g/mol, is a CATO reference standard with documented purity and traceability.

1-(2-(4-Chlorophenyl)-7-methylpyrazolo[1,5-a]pyrimidin-6-yl)ethan-1-one (C15H12ClN3O) 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. 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.
