8-Iodopyrazolo[1,5-a][1,3,5]triazin-4(3H)-one (CAS 147916-84-5), molecular formula C5H3IN4O and molecular weight 262.01 g/mol, is a CATO reference standard with documented purity and traceability.
8-Iodopyrazolo[1,5-a][1,3,5]triazin-4(3H)-one (C5H3IN4O) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; 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.
