Description

Compared with other compounds in its class, the molecular weight of 317.72 g/mol gives 3-Chloro-2-methyl-7-(thiophen-2-yl)-5-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Chloro-2-methyl-7-(thiophen-2-yl)-5-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine (CAS 866143-92-2) is a high-purity analytical reference standard with the molecular formula C12H7ClF3N3S and a molecular weight of 317.72 g/mol.

3-Chloro-2-methyl-7-(thiophen-2-yl)-5-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine (C12H7ClF3N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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.
