CATO supplies Ethyl 2-(6-oxo-8-(trifluoromethyl)-2H,6H-pyrimido[2,1-b][1,3,5]thiadiazin-3(4H)-yl)acetate (CAS 1622837-13-1), a certified reference material (molecular formula C11H12F3N3O3S, MW 323.29 g/mol) for analytical method development and quality control.
Ethyl 2-(6-oxo-8-(trifluoromethyl)-2H,6H-pyrimido[2,1-b][1,3,5]thiadiazin-3(4H)-yl)acetate (C11H12F3N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
