Description
CATO supplies 3-Chloro-5-(5-chlorofuran-2-yl)-2-(3,4-dichlorophenyl)-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine (CAS 691868-56-1), a certified reference material (molecular formula C17H6Cl4F3N3O, MW 467.06 g/mol) for analytical method development and quality control.
3-Chloro-5-(5-chlorofuran-2-yl)-2-(3,4-dichlorophenyl)-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine (C17H6Cl4F3N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. 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.
As a certified reference material (CRM), 3-Chloro-5-(5-chlorofuran-2-yl)-2-(3,4-dichlorophenyl)-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
